Teamers, in any sort of game tsb mm2 forsaken dod etc, they are just so annoying.

for example if you're playing a fighting game and you're not that good they will abuse the knowledge of your gameplay and combo the shit out of you.

Another example is in mm2 there is literally no point in explaining it because it's so common and you probably get what I mean by that.

I could go on and on about this but mostly it's the same stuff like teammates not helping you.
