As I said, it's not because you like something, that you can't criticize it.
MTW had a crappy diplomatic system, that was improved in RTW. Because people complained about it.
It's not that MTW was a bad game, it was an excellent one. But that doesn't prevent people to see the flaws and adress them.

Well, RTW is excellent, but it has flaws. Among these flaws, a too fast killing rate. Don't see what's the problem to tell it to CA.
