The last thing we need are self-proclaimed deputy sheriffs.
If you suspect someone of doing something like afk-farming, cheating or whatever just report it to the support.
Once someone alpha'd me into my back on the spawn taking out one of my weapons (me hunchie, him atlas) - I shot back once and strode off towards the enemy - while fighting I then noticed him still trying to shoot me. He was missing me though, so I lured him a bit deeper into the enemies I was fighting - as he was a juicier target and much easier to hit the enemies concentrated on him instead of me. I then helped them killing the atlas and got the finishing blow

He was quite mad at me accusing me of afking. My teammates told him I was obviously not afk but only ready a bit later. He then tried to excuse his behaviour by telling us he counted to 20 until he shot me...
We won that match - but tbh I didnt like shooting back, as I was well aware, that taking out such a heavy machine as the atlas from our team weakens us. And not only his firepower is missing, but also mine while we shoot each other.
There are many people out there who still have problems with the stability of the game - including me: I for example experience things like a blackscreen, the 4 fps drop or just plain CTDs every 10 games or so. Today out of 4 games each game one of our 4 man team dropped to one of the afforementioned reasons.
So just leave it to the support and dont try to take things into your own hands.
