Yeah the mana costs were originally meant to limit his power early, that and having long cooldowns early, and being slow and squishy... all that wasn't enough though, they ended up having to nerf everything else hard too... those mana costs were originally on his abilities when they had much better range and damage on all of them.

If it makes you feel better, he does end up with one of the largest mana pools of any champ.
