I try to make mental notes for players "playing their class" correctly and going for the objectives.At the same time I remember players who do not team play and either play just for k/d ratios or ignoring capzones.This has nothing to do with rank or even the top scores.
I bash these losers over team chat repeatedly:
'X, why go SL if you're going to camp as far from the objective as possible?'
'X, please change class so that this squad has someone to spawn on.'
'X, notice that you're in the bottom five of the team - isn't it time to do something useful?'
I can guarantee they'll get tired and rage-quit before I do. Or start flaming me and get kicked by admin,
