It's their job and they get paid for it
On that basis I will be happy to make the assumption that they do in fact know what they are doing.
Assuming that the reason people don't agree with you because they are stupid and ignorant is somewhat arrogant IMHO
Except you clearly are ignorant. This is not an assumption I am making because you disagree with me. This is an observation that I am making based on what you say. Your assumption that relic knows what they are doing is simply false. Unless of course, Relic intended that half the 1v1 map pool are unbalanced, that they intended only a handful of commanders to be useful, that they intended to make P2W commanders, that they intended to make infantry spam into call-in tanks the ideal way to play this game, that they intended to take months to fix game breaking bugs, that they intended to make OKW play the exact opposite of their design philosophy, and so on. If these were indeed their intentions, then yes, I agree, Relic totally knows what they are doing and you sir, are not ignorant.
