Intentional TK, shit talk and quitting server to avoid any possible punishment.
I was on archer alt on siege, opening backdoor to shoot 1 shot then closing it, to slow down enemy team's progress while chopping. A different Teammate near door lets 1 guy in at a time, I backup to get melee out and get slashed in the back by this very impatient guy, Lithix. We kill the enemy and proceed to do the open door and fire arrow, close door plan. Same thing, we let 1 enemy in and melee him, this guy hits me in back a second time because he's an idiot.
So I report him after the 2nd hit and he rages and decides to TK me for reporting him. Says 'bitch' at me and quits server.
