How can anyone complain about one faction as long as he didn't play it? When I had my doubts, I played the faction I thought being OP and after playing it I kept or droped my opinion, depending on gameplay conclusions.
A simple example: at one time some people complained about soviet mg spam tactics being OP. Tried it with my teammate on 2v2 and in 20 games we were defeated 2-3 times (maybe). Conclusion was simple. Some were complaining that soviets were OP in every single game mode. Tried some 1v1 with soviets and concluded that the faction was quite balanced for 1v1. And so on. But if one comes here and says "played against one faction and I got beaten every time = > this game is shit" such statement is quite improbable if it is not followed by this one: "played with that faction that I considered to be OP and won 90% of my games = > the faction is OP indeed".
I agree. Most op talk is just talk and not much walk. The ptrs-doom never happened for one thing even though the weapon team destroy was bad while it lasted. I consider the game reasonably balanced (there will always be some issues) since my w/l rate is similar across all four factions.
