My suggestion was to have certain spellcasting classes to have certain abilites:
Specialized as Healer/Cleric (whatever you wanna call it): Not being interuppted while casting rejuvination. (which would be a big one as a healer)
Specialized as Offensive Mage: Instead of duration of spell ending quickly they should be able to keep it on for 1-2 mana a second and have the spell run out only when their mana is depleted (excluding volcano and some of the heavy spells), or if they take out a weapon instead it cancels the spell + mana drain.
Also offtopic: A chain heal spell would be a cool add also
Just some ideas, COMMENT TIME!
