Change Syndra's ult
It is unbelievably overpowered for a champion to so easily get kills with a locked one multi hit ult. My suggestion is to have it be a skillshot. It gives her more room for outplay and more room to be outplayed. She summons the balls around a champions, and just like zed uses his shadow throw his q, have her use that form of skill shot. Basically the balls will surround the champion in a circle. Meaning she has to have some skill to stun the champion. The combine it with her ult. She would summon the balls, then in a mirrored attack, the balls would go towards the center, where the target is, if they avoid it he balls keep moving, till they either hit something or go to their ranged limit.
