Nerf that purple void piece of *

Increase her size + hitbox to at least match Lifeline in size. After that you can look into buffing her abilities again. Her tiny hitbox was a mistake from the very start, and makes her pretty much impossible to properly balance. I mean, she could have NO abilities and still be a mid-high tier choice due to hitbox alone.

I'd go as far as to say Wraith with no abilities is still better than Mirage WITH his abilities.
