So, his ult is basically like, god. Late game: Find a pick? Steal, press b, wait. Free fountain kill.

Or he can totally disable an enemy champion, easily making any fight 5v4, while he still gets to do work, as long as the enemy can't totally clean house, his team will win that fight. I know that it's a long CD, but all the same, unreasonable effect imo. A large reason why many champions have been nerfed is because they remove counterplay and make gameplay unfun. An ult that stops an enemy from being able to play for up to 10 seconds, an moderate to long teamfight, seems really unfun and toxic to the game.
