Whats going to happen: 1) Relic wants to milk the fanboys
2) They release commanders OP as hell for a whole month
3) 1 month because they don't want to start losing the playerbase
4) They balance it after a month of receiving fanboy money.
You forgot the bit where:
a) Everyone plays it because it's new
b) Nobody knows how to counter it yet
c) People start QQing that it's OP because everyone is using it and they don't want to adjust their playstyle to counter it.
I already know that is what's going to happen, and I'm not going to make any judgement on it either way for at least a fortnight after it comes out and probably not evern then
