He is easily the most annoying champ in the game. Reset on ult, stupid obnoxious passive movespeed. R%%%%%ed low cooldown on dash, shield that scales like a damn janna +5.
Seriously, he is just cheesemode. One of the only melee assassins who gets soulstealer because "muh skillz"
I think his passive movespeed needs to be switched from every third hit to whenever shielded. Right now it is the sole reason he cannot be punished. He is literally an unpunishable assassin.
