Confused as shit on how to build her, play her as an AP caster, but still have the idea of being a support. There's not enough utility AP items.
But she does a lot of damage with Q alone. Holy ****ing shit.
R+W is by far the most lackluster part of her kit I agree.
R+E is definitely strong as shit, especially considering it scales by her mantra level, so immediately at 6 and 11, the shield and AOE damage is really frickin' strong even with no levels into E itself.
She's fun to play, the feel on her is pretty okay, though she seems more standard AP caster than the support mage they said she would be, more akin to Orianna than Zilean.
