Since new cards were added in the patch it is sadly wrong again^^

You also have to keep in mind that reforging is finite. Like Windhunter said, 750.000 cards have already been reforged. While that number will rise, I doubt it will be double in the same amount of time. Reason being that most of the active players have now reforged most of their inventory, and simply dont have enough cards left to keep up the reforging pace. Once everyone has burned through their backlog, you can expect the market to settle down a bit. Its the effect of releasing a drastic system like this one year after a release. Im really curious how the market will look 1 year from now. 

have you checked?
specifically:
[Open] Balance Developer
[Open] Game Designer

try "promo:1" 🙂
For values (health, attack, upgrade, charge, copies) you need to use "=", but for attributes (a.e. promo, flying) you need ":". Think of it as true/false for 1/0 rather than the number.

Maybe an ability range of 50m siege range on a building used mostly to speedrun feed or kill void recycle ones own units at close range is excessive.
 
This is such a minor issue, but the large range is mostly abused for denying allies ground presence. Unless speedrunners need the range that high, reducing the range will mostly only hurt decomposer trolls without hurting functionality.

If you think balancing cards is easier solution, why not apply for "[Open] Balance Developer" position, to try out for yourself?

How are we supposed to fix it, if we do not have source code for it?

As announced in our 11th community update, we decided to open source wav_to_snr (repository link). This is a very simple application that allows you to convert audio files to a format that is compatible with BattleForge called SNR.
SNR is compressed a lot, and it is lossy compression (over 70% of data is lost). Sample count is the same as WAV, but for most samples only 4 bits instead of 16 bits is used for the value, that means 16 possibilities instead of 65536 possibilities. It is not that bad as it might look at first look. There is some function (difference from previous 2 samples) applied so the dynamic range does not need to be that big, and only precision is lost.
Currently it works this way: for each block of 32 consequent samples it tries all "configurations" and calculates all samples in the block, then pick the one that have on average smallest difference from the original sound. The problem with this is that if the original audio is decreasing at the end of block, but the compressed one is increasing it, it can still be the one with smallest difference, and if next block start lower than the source, the difference between the last sample of the block and first sample of the next block will be even greater because of that.
In theory "configuration" should be picked so that whole audio wave is as similar shape as possible, instead of absolute difference for each sample averaged over independent blocks. But comparing shapes of waves is much more complicated thing, requires much more computation time, and what is most important it is much more complicated to write.
So if anyone will improve the algorithm it would be great 🙂 right now it is kind of unusable for voice 😞 but for some simple effects it sounds kind of maybe acceptable.
If you want to just play existing file check out:

I know this one got overshadowed a bit by the new-patch-hype, but we would greatly appreciate the help from the community for making the implementation of voicelines possible. We already have two cards fully recorded and ready to go, with others in various stages of recordings, but they are currently on hold because of the mentioned issues. 
Please help us out 🙂 

🤔 what "hostility"?
I personally do not like the reforging, so I do not need to hear how people like it.
Position of "Balance Developer" does not require any technical knowledge, and usually applicants get to try it before their application is being processed.
It just need crazy amount of time per card. And there are 1000s of cards.
I did not ask about position of designer that have more to do with re-balancing the cards. I would say these positions also not require highly technical knowledge (depending on how you categorize math).
I hope it will not sound aggressive to you (again), but how you can judge a concert if you are not musician? All concerts I heard in television was just some people doing noise, no useful information, no fun, so I have no clue why would anyone want to watch that.
And to be honest I feel the same about any soccer game, you get score, so you know who win, what else would you want to judge one it?

🤣 this weirdness is intended, but do not ask me why I was given some explanation I did not understand.

Intended to make people with OCD go crazy?  It makes no sense....LOL

I see where Demiron comes from with his observations regarding the forging system.
I played BF when it first launched and had 10's of thousands of BFPs because of buying cheap retail packs.  Cases of them actually.  I had every card I wanted and many of them.  So many that I had a huge shop selling C and UC for gold so new players could make complete decks.  I would have LOOOOOOOOOOOVED the forge system then.  But what would have happened?  I'd probably have stopped selling my C and UC for gold and put them in the forge.  This would make it harder for a new player to have a dependable path to solid decks.  Instead they would be entirely at the mercy of rng and grind.
 
Now I'm back to the game maybe six weeks.  I've been buying commons on the AH to fill out my decks and saving toward more expensive cards that I enjoy playing with.  The prices for those things have now doubled or tripled or are simply not available.  The hill new players have to climb just got much steeper.  If I'd been playing for a year or more I would be ecstatic.  A new system that lets me use all my unwanted cards with potential to get something better or different.

Honestly with how many cards are in the game the time it would take for a new player to have 4< of a card to begin forging is insane.  
 
Another observation of mine is that the color output does not make sense.  If I put in shadow x3 and fire x1 it would make sense for the output to show 75% shadow and 25% fire chance of the forged card.  Currently it is 25%, 25%, 25%, and 25%.  If I put shadow x4 then it shows 100% shadow output.
 
Appreciate all the effort that went into this as I think it is brilliant.  Hope we can find a way to balance the newer player's experience though.  It just got much harder to get cards for them.

fixed client so it can handle up to 127 mails after next patch. (It is still up to server to chose any number that is not higher than this. I guess something round like 120?)

Tweeto continues to do such a bang up job emulating the artstyle.
As for the name, I would lean a bit into the naming scheme of less serious, rugged names that you can imagine being bellowed across a tent while everyone is getting drunk. Things like "Boom Bomb" from Artillery. Bandit Launchers "Firebug". Corsairs "Big Fat Cannon" and Rioter's Retreat "Uproar". Descriptive, visceral names that you can yell even while drunk on gold and booze. "Treacherous Path" sounds a bit to lofty to catch on with Bandits.
And a different name would help differentiate the card from "Mine" and Soulhunters "Minefield".
Name: Desert Carpet
Ability: Toeclippers
The idea is based on carpet bombing as the area is similar. It is also something that I can imagine crafty Bandits saying. "Let's lay out the desert carpet for these folks.", making fun of the more civilized nations and their customs.
The ability itself is the more grounded version and represents a type of dark, macabre humor I see as very fitting for Bandits. Since mines are equally meant to cripple and kill I imagine Bandits might have fun ironically belittling them as Toeclippers. Knowing fully well how devastating they really are. "Harhar, hope they don't mind some Toeclippers."

based on your description I would more likely guess ti to be an network issue. But what I can say for sure is that it have nothing to do with .net, because game itself does not use .net.

If you were able to trade up lower rarities to higher ones, then the excess of low rarity cards would get diminished to the point where it's actually worth it again to put them into the AH.
And if it turns out the supply becomes so low that the prices, even for Commons, become unreasonable, then opening Boosters would be very lucrative once more, since even the crap cards would recoup some cost. Which would then increase supply again. Right now the value of an opened booster is determined by just a couple of cards that are valued for more than multiple boosters. Every booster not containing one of the top tiers is a big loss overall at the moment. So with enough economy participants, it should find a new balance.
But the most important points are that it would stop endlessly inflating Ultra Rares by increasing supply (as people trade up) and the bottom tier Commons/Uncommons become a bit more valuable as the excess gets culled. Being able to trade up should have the effect of lowering the price ceiling while giving every card inherent value (if only as material to trade up), raising the price floor. It would also serve as a soft BFP sink, as cards are just another manifestation of BFP (they get generated through boosters, which are generated through BFP).
Actually, I think a quick-sell option of turning cards directly back into BFP would be detrimental. It would generate even more BFP, which is the last thing the game needs.
