I like the balance of exciting heal checks, DPSing in the background, and occasional bursts. I like how all the healers have unique abilities; although some things feel similar, there's enough differences that I can switch between them to get some extra variety in my dailies/weeklies. And recently, I've been really enjoying the Ultimate challenge in Dragonsong Reprise. I'm glad I'm playing WHM for it, because I've got a lot of quick healing tools, and don't have to manage as much stuff as AST while doing mechanics, so it feels very smooth and powerful.

Anybody else want to share some healer positivity?
