Personally, I think Dancers as healers is a bit more interesting. Dodge tanks could probably be tied to a bunch of different concepts, but Dancer is about the only healer I could see working with DoW, and I would like seeing a healer in DoW and a tank in DoM, silly as it may be. That and I found the concept interesting, would give me a reason to level Pugilist too, since that's a likely place for the Dancer.
