Attention clueless idiots.
DO NOT take an important role in the game if you don't plan on playing your role, or if you do not know how to play that role. I am sick of people taking the commander role and losing the game for their team because they do nothing, not even communicate. When asked repeatedly to switch by their team members they ignore those requests. This is not Call of Duty, you do not pick a class for the weapons, you pick a class to play that class. If you're a machine gunner, your job is to sit back and suppress the enemy, to either cover the advance or stop attackers. If you're a sniper your job is to hide and pick off priority targets. If you're an assault soldier your job is to get in close, clear areas and take objectives. If you're a squad leader your job is to use smoke, mark targets, take objectives and act as a spawn point. If you're a commander your job is to talk to your team (preferably with a mic), to call in good arty, to force respawn, to use smoke and to call in recon, sit by the radio and inform your team of enemy movements.
If you don't plan on doing any of that, then be a freaking rifleman. Winning and losing depends on people playing their roles and I (and many others) have had enough of clueless CoD kids coming on, stealing important roles from people who do know how to play and losing for us, because they don't know what they're doing. And in my experience, they always refuse to listen to their team members when we ask for them to call in arty, or recon, or use force respawn or switch to a different role.
Play your role properly, or don't play an important role. Please.
