Syndra ult honestly needs changes.
As one of the few point and click nukes in the game, its horribly annoying. You either need to start barrier and play passive, or just flat out crush the laning phase with minimal jungle interference.
The worst part about her ult is, it doesn't matter how many Q's she misses, they all add to the damage. Perhaps something along the lines of making the ult damage reliant on how many orbs currently on the ground actually struck a target?
completely negates her ult. And lastly it doesn't matter how many orbs or out because her ult maxes out at 7
