In a ranked solo queue game tonight on pbe I experienced something very strange. There was a teammate of mine who could chat for me! I would remain silent in team chat but i would look down and see:
[ALL]:Nocturne(Niloxam); blah blah blah...
I thought I was being hacked. Turns out that the Vi on my team, FizzBG, was the person chatting for me. The only info I could get out of him was that he was on the Mac client. Fortunately he didn't say anything too damaging, at least not to my knowledge, but this could pose a problem if not corrected before it goes live.
He was playing Vi (no skin) and I was playing Eternum Nocturne.
People could theoretically get reported and punished for things they never said.
