So frustrating!

Why are there so many dickheads in this game? I've played 4 matches this morning and was being repeatedly bullied by my own team mates in 2 of them, pushing me out of cover so i get blown up! where's the sense and logic in that? A lot of players seem in it for themselves and couldn't give a crap about actually winning the match, just caring about how many kills they can get, even throwing team mates to the wolves to achieve it. If any of you are reading this...go f*** yourselves!!
