Morde's ult is actually one of the dumbest things in the game
Beating him in lane? Maintaining consistent ward coverage to make sure you don't lose your advantage to a gank?
He can just ult you, miss every skill shot, and run around with his passive + shield as his jungle walks into the lane and positions on top of you as you come out of the ult.
This ability has so many things wrong with it.
