Katarina Suggestion
When you do change Katarina with the Assassin update, can you make it so Shunpo "disjoints" attacks? Yes, this is basically copying Dota 2, but hear me out. (Disjointing is where you completely ignore a projectile's effects and damage if you happen to blink away).
Since you removed ward hopping with Katarina, could this be a replacement for her so she doesn't get utterly annihilated while jumping around opponents? Any hoaming projectile or attack will always hit her even if she Shunpo's. This is notable with abilities like Hecarim's W; even if you Shunpo away, you still receive damage and the CC applied to it despite not being there.
