Well, technically , maybe you could tank for 10ish seconds before you die?
So they could use Collaborator >> Spirit Bond >> Eyes on Me and give themselves a 10s tank phase. They might not survive 2 hits from lets say Kefka, or some serious NM, but they could potentially survive a weaker boss for a few seconds.
I updated and added "Reverse Flourish," and what that does is: it either causes their next Curing Waltz / Aspiring Waltz to Cure Two times, or of course, make their next Weapon Skill hit twice.
So they could potentially save a party wipe, or even give MP to Mages when they're in desperate need of it.
I wanted to make Dancer (DPS) into a more fleshed out Support/DSP that took inspiration from MNK / NIN / and the Final Fantasy franchise, and of course, FFXIV style.
Speaking of Updating, I did tweak skills etc. but again, hopefully feedback can flesh this out more; even though people either want DNC to be a healer or tank?
