that's what lag causes to you, on his screen you were close to the edge, so since you left the ring on his screen you end up losing. That's what makes it so hard to face chineses.
He tried AoE stun, but my antenna beam got him first, then i used EP drain on him right away and hit him with that.
Then he dashed to the edge, armpull me , i tried to walk away right away, then he fear me, and whille im still inside, got the message out of arena... :S
