Inspired by @RadicalX, here's thread to put your controversial PvP opinions, and we can rant and go off-topic as much as possible. Example subjects might include things like "why deathglider is the most underestimated unit in the game," "why Pure Fire doesn't lose the Pure Frost matchup," "why fire stalker needs a nerf," etc. This is supposed to be serious though, so make sure to justify your statements.
@RadicalX Let's give you some room to explain some statements you've made elsewhere:
1. Why are thugs unnecessary in a fire t1?
2. Why are defenders underrated?
3. Why does stonekin need to take aggressors?
And everyone else: these are some example topics of controversial opinions. They may not even have to be super controversial--just something that the majority of players have a different opinion of than you (even if all the top players think the same thing, it's still "controversial" if 60% of the rest of the rest of the PvP playerbase doesn't agree/never thought about it). This is a place to learn!
I'll start with an opinion of my own: Mauler MAY be a better use of a deckslot than firesworn, in a fire-nature deck (esp in 2v2, depending on your partner). I'm not necessarily saying that statement is true, but at least it's more correct than a lot of people would think. There's only one L unit in t1, and you have lots of ways to kill it without using firesworn. Shadow does it all the time, and in the worst-case scenario, you can counter one sundy with another, but also, no one ever uses a sunderer against fire unless someone messed up, because everyone is afraid of the firesworn. So unless your opponent knows you don't have firesworn, you probably don't actually need him. In t2, you have access to mauler. If you're staying t1 vs t2, this is the biggest problem with not having firesworn, but I've usually been fine. Body blocking, scavie bites, and mortars are usually plenty.
In t2, mauler is useful because it helps against some bad matchups (aka stonekin). Stonekin and Pure frost have a lot of ranged units, and sometmes they might get a squad of defenders to sit and pick away at your well. 1 for 1, mauler beats defenders. Mauler also helps in t3, because it really shuts down ashbone pyros (esp with root).
In 2v2, you and your partner usually have enough dps to be able to handle a sundy, especially if you're careful (or have a lightblade). In 2v2s, spamming ashbone pyros everywhere is a pretty common tactic, and being able to counterspam maulers wins a lot of games underneath ultra-high ELO, because most players can't micro 5 spots at once. They sit out 5 ashbones and expect one will work, but if you set out 5 maulers, the other opponent usually won't even know how hard he was shut down before it's too late.
Most importantly, mauler beats mountaineer, which IMO is the hardest card for fire-nature to deal with. And I'm not necessarily saying that I believe mauler is better than firesworn, I'm just saying it's not as obvious that firesworn is better as most people believe.
