Dancer - Debuff Mitigation Healer

[ErdrickLoto]

Then brings in the question, using MP like a Bard to keep this buff or are we using TP? I'd assume TP as using a healers MP would seem silly but then a 2nd question on would a Bard/Ninja/Ast be able to keep a dancers mp/tp boosted to prolong the effect or would it be like a DRK's Darkside and prevent recovery till its turned off? I like the idea myself and I see a Dancer as a constant healer or debuffer for the group, but wanna hammer in the details.

It would be TP, since, as you said, using a healer's MP would be...unoptimal. Same reason why DRKs use MP, not HP.

It's supposed to be like a reverse-BRD, so you could use a TP-refresh to prolong the duration. The effects would have to be weaker, obviously, but at least on a micromanaging level it would be a bit easier to manage.

I'd honestly rather see Dancer as a tank or dual spec. Possibly heal/tank depending on what's needed. I think dancer tank would just be awesome.

Dancer seems like it would be an evasion tank if it managed to land the tank spot, which would be very RNG-based. Given how disliked the RNG aspects of MCN and AST were (on launch, at least), that...seems like a bad idea.
