Lot's of different playstyles made the game different every time I played. The thing is that I really want an american commander, so I keep playing them to get one to drop. I don't want to play another faction til I get at least one american. I don't want to switch to another faction, because then odds are I'll get one of the ones I don't really want. So I'm stuck playing the same three american doctrines until I get one.
Out of curiosity, what was your motivation to play the game before WFA expansion?
It's not that I would quit the game forever, but I was already an alpha tester and played americans a lot already. So I might just play other games til the systems fixed.
