At the start i am gona just mention, if you demand some kind of behaviour from others, be sure you arent acting in opposite, otherway whole your message might come pointless.
I know this kind of players exists and usualy there is no way to prevent them doing that, but i am not here to solve this increasing problem, its you who should try to find/suggest solution at this point, becouse mass scale frendly fire isnt proper solution at all.
It is impossible to fix it, cuz people are FORCED to play together, people dont like to be forced to do somthing that they didnt want to.
Whos forcing you to anything?Don't want to play with other "noobs"?.Fine, there's a solution to that.Play factionless,kill whoever you want but don't expect you'll have same treatment as those guys in faction.Meaning,no room to stash your stuff,you gotta find somewhere else to stash it.no help from others, but hey,you can go on killing spree against everybody because you know,BBS and all other pros don't need anyone else,others are just in their way.If you dont like it that way, FO2/Reloaded/TLA is in other direction.And for those who start TK perma ban.As for other members looting your stuff.Why not implement that for first few minutes only squad members can loot each other,and after timer is off,it's FFA.
