Yuumi and how to improve her

Sorry everyone im just gonna give my breif thoughts on how to buff her without buffing pure damage

Give her scaling defense (mr and armor) when using her passive shield successfully.

Make her able to cancel skillshots after going in vulnerable like fizz can. Do the same with turrets. Turrets should not be able to target her. She should only be damaged by things that follow threw untargettability. (Kayn R, ignite, Zed R pop) Not on click skillshots (teemo Q can hit her threw invulnerability, so can other skillshots)

Q should be AoE

Remove E stacks like u did to aatrox and make her E reset when attaching to low hp allies (30% or lower) once every 2 or 3 seconds. Make her E 10 sec cd. Scaling down to 6 or even 5.

Make her R shoot faster. Like a lot faster.

These are just my ideas to make her better and not so shitty to play. Hives her game carrying mechanics
