It's kinda okayish in 1v1, there is better choices for this format, but in other formats especially big ones its very hard to play against it. 4v4 with 2 or 3 CASes is nightmare especially in premade vs premade. The main problem is that most of AA can't do anything against CAS.
Agree, the problem is it is utterly impossible to balance a game for every single game mode. Relic has made it clear a balance for one versus one primarily and that is as it should be. You are never going to be able to balance large team games and one versus one without two whole separate installs because there is so much more fuel and ammo in 4 versus 4 for instance that you can simply spam lots of things that would be impossible in one versus one
