Scholar: Give it all its DoT spells back.

Astrologian: Give us either its old HW card system or a better system where each card does more than build up damage and skill/spell speed.

White Mage: More Blood Lily related damage spells. Maybe an alternative use of the Blood Lily build up system where instead of using the free healing spells to build it up, it gives us free attack spells instead. I remember somewhere her mentioning an idea just like that.

Sage: More laser attacks. That is all, lol!
