I really wish a melee healer similar to Holy Paladin from WoW would be added to this game. It would be cool if it had a 1-2-3 rotation just like tanks as well.
I could see concepts for either a pure hp or shield healer.
I know for sure that a 1-2-3 rotation would be a lot more fun than the current state of healing where you're just mashing glare/dosis/malefic/broil and reapplying a dot twice a minute...
