I feel your pain, makes me wish team killing was allowed again. I've been killed so many times because my exit route was cut off by someone with no friggin situational awareness it's pathetic. Been blown off the map in mid jump a few times in mid jump because of loose nades .... really, you throw nades near a team mate in CQB .... the list is endless.
The most obnoxious kids play any more. Jump in front of your line of fire, Bump into you knock your shot off line, block a door way aka your escape route, ridiculous. I want team killing back.
