I like the idea of the first option, but maybe to a lesser degree. It's a thing I've been thinking about for a while, too.

How would you feel about:
  • Mitigation/damage-reduction tools being stripped from non-support oriented DPS jobs (so things like Feint, Addle, Crest of Time Returned, Tactician, etc. being removed from NIN, DRG, SAM, RPR, SMN, BLM, MCH.)
  • Jobs like MNK, BRD, DNC, and RDM keeping their support tools, as well as their unique mitigation/healing-up abilities they already have, thus contributing more to their supportive identity (Yes, I view MNK as a supportive job, even if only in some identity that doesn't exist anymore. It just has that feel for me)
  • WAR and GNB's party-wide tools (Shake it Off and Heart of Light) NOT being removed, but toned down a bit, maybe with Shake it Off's barrier effect being removed, OR have it apply ONLY to the WAR. This means tanks like PLD and DRK, which always had that sort of "protect the weak" identity from earlier in the game, get to keep their party-wide support as-is.
  • All Tank's 'Reprisal' being adjusted to only effect damage done to the tank that applied it.

It might not be perfect...... and it isn't, but thoughts, adjustments?
