Speaking more from a PvP perspective, I'd like to see hybrid classes lose their ability to cast and spam heals (IF they are specced to dps). I personally would prefer healing to be situational and only available with a cool down attached to it (eg Ancestral Guidance, Natures Vigil). Spells like healing touch, flash heal, surging mist etc should only be available if you are a healer.
What are your thoughts?
