It also depends on someone's definition of a "good healer." In Ex Roulette content your healer should be able to be in Cleric Stance more often then not, by my definition. Tanks that don't mitigate damage well with CDs or Pull excessive mobs with a low AOE dps party are an exception (Think Pally pulling 10 mobs with 2 ninjas ;_;.) Its just a waste to have so many nice AOE/DPS skills as a healer and not use them to their fullest! D:

If you can keep your party alive and do the best DPS you can do, you're being a great Expert roulette healer. :3
