He's the latest broken af rework tragedy the Riot team has put out(not counting garen since his changes arent on the worlds patch).
He's been banned in 42 out of 43 worlds games so far. Banning him wastes one ban that a pro team could use strategically. Basically forcing red side to have 1 less strategic ban available every game.
Its also boring af to watch, since you know 99% of the time, first red side ban is gonna be pantheon.
