Situational and Instant Cast abilities. If you want to make healing more engaging, other than cure, with sprinkles of stoneskin and protect/shell in between, you need to have more engaging moves with some moves being instant cast (ie: no cast bar!) It would be great to have some type of self buffs that increase healing potency for a short period of time (with an animation that lasts the full duration of the buff), as well as moves that add some flare and fun for healers.
Why does Stoneskin take so looooooooong to cast? And why is the recast time for Chainspell 3 whole minutes? Let's allow conjurers a system whereby they can chain spells through skill of game play and optimal gear, not just some ability on bar.
