Her damage is okay, imo, it's all based on skill shots so it works that when she hits them she is rewarded.
Her only problem is the fact that she has a 3000 range AoE nuke that has 700 base damage + 0.75 of AP UP EVERY 24 SECONDS that isn't okay. You can literally use it on creeps to farm and have it up whenever you need it. Ridiculous. And it's not like without it she's useless or anything (like with Karma without Mantra), considering her utility and range plus damage of all of her abilities.
