The sarcasm isn't warranted
It's very much a game of team coordination where the power curve is exponential but also can have huge turnarounds since buildings are fragile but drive the economy entirely
So naturally you have to know how to play your specific role or it can throw the game for everyone else
It's not casual like Command and Conquer or something, but nor is it incredibly sweaty like StarCraft or DOTA
Is command and conquer considered casual?
I feel like whether a game is considered sweaty or casual is more dependent on the game mode (e.g. ranked vs normal, UMS vs ladder etc).
