Gameplay - most of the time it's walking and looking for enemy, rarely happens when game is dynamique, very often there're ~10-12 players on server. If there were more transport vehicles ariving at specific flag would be quicker, though more shooting and more intresting gameplay and more players. You may think this is irrevelant but think what will happen with bf if not vehicles availibility.
You know, comm rose which is easy to learn by pressing one or two times comm button. Huge part of game is simple communication but it's impossible with this thing. Why do you want me to play Rainbow Six when i don't want to play it?
500 Bp - you know, there're in game also weaker players than you in which case 500 bp may be a lot to spent for something which can be used only for couple seconds - totally not worth it.
What exactly distracts you from real in game? Something which blows up far, far away? I'mnot writing about total war shots and bombs every second, i'm talking about something like it was in CoD2 (if you remember). Also those war sounds will mute itself when entering into building.
