I totally agree with @LagOps. Battleforge was a mix of card game and RTS game and that made this game unique. When you give everyone permanent access to top tier decks then you remove very important aspect of this game (even if it only affects PvP decks).
In case of PvP you basically treat cards not like a cards, but like a diffrent way to visualize troops, buildings and spells and treat collecting as something completly necessary that has to be done to enjoy PvP - I completly disagree with that.
What is the difference between Skylords Reborn in current state and other RTS games in terms of PvP then? For me the difference between Battleforge and other RTSes was that you had to earn your deck and upgrade it to become better and better. And that was the only difference I noticed, but it was the most important difference for me!
Someone on discord said that these free PvP decks were made because of lack of people intrested in PvP, but don't you think that it was caused by Beta? People knew that there will be hard reset after Beta is over, so less people were playing the game. Maybe consider removing the decks for 1-2 months and if the playerbase will grow then I don't think there will be a problem with PvP queues even without free PvP decks (like it was in Battleforge), on the other hand if the playerbase won't be big enough, then reintroduce them to the game.
