Personally, I find spell/skill casting just fine where it is, Hexers spells are so costly due to their insane utility, and the high damage output they have. On top of being spammable as long as you have focus, the high costs on them are justified. Evoker spells aren't that costly but have decent damage output, only mitigated by resistances and sanctity, making them less than favorable but still usable for now. Most melee class skills aren't too costly in trade for their use and output. This all being said if you don't put any points into willpower to cast abilities, that's your own fault.
