Idea to make healers more interesting
So in the lore, a conjurer must take life to balance the life that he/she gives. What if the conjurer was given an ability ("Divine Wrath" for sake of argument) that charges up as she heals. When the gauge on the attack hits full, he/she can use it to do an incredible amount of burst damage all at once, instantly killing a trash mob or heavily damaging an elite.
One thing that a lot of healers like to do is flip cleric stance on and cast their offensive spells for some damage when the rest of the party isn't taking much itself. It's arguably the one thing that makes healers more attractive here than in other MMORPGs, and giving them such an ability would make things a lot more interesting.
A similar power up ability could be utilized by the scholar in respects to enemies eating through the galvanize buff.
