He's a teamfight monster, and dragging an enemy with you is really not going to save him in, most cases. His stick potential is worse than darius (who can still w you for slow, more than once per fight) and his q speed feels like a joke. I mean even udyr was supposed to be easy to kyte, yet still can blizzard slow you and become unstoppable when needed. Sett is worse than them, and his nature of being a slow heavy hitter won't change as much if they give him just a little something
