I am sorry to say this but maybe you're playing the class really wrong.
It's not that it's unplayable, it's that it's not acting properly.

Though I've already posted in a more productive thread on the issue, I'll clarify for you:

Regen ticks, poison ticks, spell applications, spells unapplications...ALL drain MP. They are not supposed to, and if you ever have an AST throwing out regen effects and card buffs on you, you WILL feel the difference.
