May I suggest a meaningful change to Summon Aery?
Change the name back to Perxie. It was way better.
That's honestly the main point of this post, but for the sake of making it fit into Gameplay... I would like some kind of change, but I don't know what.
The main reason is that often time I don't take Comet just because I think "Why take Comet, that can miss and is only proc'd by abilities and on a delay, when Perxie can't miss, is proc'd by abilities and autos, and seemingly (maybe it's just my bad fps) comes out faster?"
