Ever considered giving Jayce more skillshots?
With all the Jayce is OP discussion going around, no one seems to suggest giving him more skillshots
Have you considered that his only skillshot ability is his cannon EQ combo? Everything else is point and click that you can buffer.
His EQ combo certainly takes skill to get off good angle snipes, but it's designed with a huge distance range that most champions in the game cannot retaliate from equal distance, and Jayce is not usually punished for missing it since he's at such a far distance that the cooldown window for using the ability isn't able to be used against him. He just waits and does it again and again
I mean this sort of change has happened plenty of times before. Remember when rengar's bola was a point and click ability before being changed to a skillshot?
