User blog comment:MonoKirisame/League of Gensokyo - Byakuren Hijiri, the Great Sealed Magician/@comment-4296199-20130411161215/@comment-5860569-20130411182601

She's more designed as a mage, but with utility. Also, her higher cooldowns are supposed to balance her out. Nasus' Spirit Fire does not grow outward and might not deal this damage. And it doesn't reduce magic resistance.

As said before, she's designed to be more mage-y. The passive can surely be well used as a poking tool with ranged attacks as a support, so it's not useless. I'll probably nerf down W. The Mana Cost on a maxed W is absurdly high though when you have alot of mana and it's full.

tl;dr I'll edit it a bit, but I won't be taking in alot of changes you said, because I think she's almost fine as she is right now.
