So yuumi 
in lane is extremely annoying and at times "stupid". She can technically avoid all incoming dmg during fights just by press w without consuming any mana. Also, her ult and Q also comes up way too fast. I suggest either have a cooldown on her w or make it so it consumes mana. Lastly, I would to just suggest that to increase the cd on her Q and ult, because the cd just feels too short, like she's able to ult during every single fight.
Heckin Support4 votesShe's a support, they have ult's that are meant to be up on team fights, also increasing her Q CD would make her lane even worse since it's her only way of interacting with the enemy and it's already reasonably high early levels, and later levels she needs it since it's one of her major ways of peeling/catching people out.
She might need a nerf, but cooldowns are not the way to go.
Uncommon Hippo1 votesyeah more toward the route of her mana pool and changing her skillshot to make it less reliable, or dropping the slow off of it, it simply has too much range and is practically un-jukable, it should not have a slow, or should be more difficult in some way, or just have a lower range. a good way to implement this would be to increase the speed of the skillshot and decrease turn rate the longer it flies, making it easier to juke, but still usable if the player predicts the movement of his opponent and uses the increased projectile speed to tag them with it.
also her mana regen is a large problem. she probably has the highest healing output over the course of laning phase out of any enchanter simply because other supports go oom after 4 casts of their heal or so and yuumi can do maybe double that, with the heal increasing the lower the hp of the target. makes it feel like youre basically trying to fight her mana pool instead of trying to outplay the opposing laners.
