I think coin flips are the worst possible thing to do imho. Not just because of this particular example, because I don't know what has happened between Dre and Kennen to begin with, but in general, in tournaments. If one player has been, even if only very slightly, more active than the other player, he gets the act win (which seems to be the case with M Dragon vs Omanyte for example), but if both are equally inactive and neither of them deserve the act win, both players should be DQ'd imo, and the player that had to face the winner of that matchup in the next round, is just given a bye. That's the most reasonable thing imo.
