The figures depend on the damage you do. For example, I hit three caster minions with my Q. I do about 50% to all of them, but it's reduced to 33% for each. Meaning I get 50% mana back. The large regeneration off of minions is something I don't feel is a big problem with his passive on W regenerating such a large amount each second.

Q, E and R require percentage costs as his W pretty much makes any reasonable flat cost a nonissue... but now that I look at it he will likely really struggle to keep his mana up in champion fights, especially if he can't keep hitting multiple people at once with Q. I may need to change something there.

He can absolutely be a mana tank, lol. Though I'd probably not get a FoN since he doesn't really need to stack health at all. I'd go for Abyssal instead (see that all his spell ranges are within the aura =D).

I'm a terrible designer, if you haven't guessed. xD Though I do love that W...
