The Multi-Aery Problem
If more than one person has Summon Aery, it can be a little tough trying to discern which one is yours. I play only a lot of support and being able to run towards and pick up Aery is kind of nice. It's less nice to see that Aery isn't jumping back to you because that Aery in particular belongs to the other support. While this isn't a huge problem in the face of everything else, it would be nice if the enemy Aery was marked in some way.
