It just happens I was there and saw what happened, and no admins were present, to my knowledge.
What would you do, say nothing?
You can say things without sounding like a douche, believe it or not. Tai Feng has the right to being pissed off considering Panos was harassing him for so long. If it was me being antagonised like that I would have done a bit more than just try to defend myself, I think most people would have too. Panos is a giant asshat, don't understand why you need to interfere on his behalf.
And I don't see why you need to attack Tai Feng when he's been long so gone, he's been playing longer than you have too.
Anyway, Tai, it would indeed be a shame if you left again so shortly after you've come back.
