I have been playing online and a few things i find very anoying

one there are time when I start to shoot people before they even know it and they turn around shoot me 3 times and I die

I hate when people join a game then leave today it was 5 on 5 4 of my so called team mates left it was 5 onto one just kinder pointless playing at them odds

is there any reason for the first one am i doing something wrong

go for headshots they do alot more damage then body shots, and also use appropriate guns, like if your going CQC, dont pull out like a carbine with all weapons, use the auger, or shotgun, or if all you do if use the sniper and you are an amazing accuracy like me, then use the sniper, but ALWAYS AIM FOR THE HEAD,

ps. if your fighting chimara, use flamethrower at close range, they lose health when they overheat, so get it........
