So you say yy2 defeated darksate in semi finals and left the server in the finals because he was loosing?
That's pathetic and stupid as shit. He doesn't get tc anyways and that way he doesn't even get Qi.
And that's all that can be said anddone. He might had to go offline quickly for real life reasons or stuff like that, you can't ban him for leaving, although (as I said above) he'll be known as a pathetic "player" now.
About your 500 tc. You have 26500, you shouldn't care about 500 more or less in my opinion xD
