Back when people where praying for dancer to be a healer I played with the idea of it being a healer that could use melee dps combos to build up resources that they spent on their ogcd heals. While also having access to a set of stances, one that made their melee combo come out faster and gave them additional resources on crits, and one that allowed their gcd heals and their ranged attack to build said resource for scenarios where mechanics force them out of melee.

The idea being that they still would get more out if they fought in melee but would not be screwed over if forced out of melee to handle mechanics. Even emphasizing this by giving them a gap closer and a leap back that would also instantly switch you to your appropriate stance when used. It was fun to speculate, but mb a concept like that could work for a cleric style healer with like a mace or something?
