Yuumi W and Aery
It's not gamebreaking interaction but an odd one non-the-less.
So Yuumi W can translate into very free proc of Aery. It has little cooldown, no Mana cost and it always procs Aery, even when you don't have Passive shield, presumably due to the W Passive damage buff.
If Yuumi would, in distant future, prove to provide way too safety and sustain and would, in distant future, require nerfs, a mini-nerf could be making the W Passive buff exception so it doesn't apply Aery whenever it can but instead would need to consume Mana from E or be gated in cooldown by Passive.
Just a thought.
