They use her passive as an excuse to give her terrible mana regeneration.

(Click the down arrow next to the tab that says "Value at 1").

She has the second worst mana regen next to taric. That's what they did to aatrox. They made his stats low, so his second life and lifesteal will hopefully compensate for that, without making him too OP.
