I like to have at least one class with sit-rep. So I always alert teammates of portable radars, care package traps, etc. Even if I try to take a portable radar out, but die in the process, I give my teammates a headsup.

If people could do the same, we have a better chance at winning the match/objective. But people tend to use mics to either wait for someone to talk smack about them, or do the smack talking themselves.

The only time I meet super chill people who watch their teammates back is late at night.

Oh man, I feel you. Not just capture the flag, but all gamemodes. I don't get it when people let an enemy sneak by them when they're camping for whatever strategy reasons, just for me to get killed, pisses me off. At least let me know to turn around and shoot them.

Actually shoot people when you see them instead of watching me die and then finishing off the enemy so you can get Avenger or whatever. That drives me nuts to no end, I'll get shot by a guy who walks past 2 of my teammates and they don't even so much as pull the trigger until after I'm dead.
