Draven is out of control, and destroys what TFT is all about.
No champion in this mode should be this powerful WITHOUT synergies. Imperial/Blademaster synergy only makes him slightly better. He can easily be played as a one/two star, get a few lifesteal items, and solo carry your team. Are we just going to ignore the fact that a champion exists which doesn't even need synergies to be one of the best in the game?
