And now you get why I want it. Dancer's in XI were, from what I gathered, a TP-based healer, which put them close-range. If they have to mix combat with the dancing, preferably with several aggro removal things (punching and healing (or stabbing) is liable to get enemy attention often), personally it sounds like a lot of fun. If they just have a backrow dance to heal kind of thing though, it would be pretty boring, and I wouldn't be in favor of that.

The only concern is making a viable healer when it isn't the main class. If they tweak Monk enough then maybe it'd be fine, but it's hard to see with just a little tweaks. We'll need to see how second Jobs go overall.
