Your ambitions aren't for balance, but for mage superiority. I'm not denying there are inequalities between the classes, that predominately rest with resistances, but infinite mana makes no sense in GK, or any MMO for that matter. And I'm quite certain infinite mana is a taboo, in most games that utilize mana, in general save for very short periods of time at few occurring instances.
Cube's proposal,
