Not a big accomplishment, but went 80BLU/40WHM to Salvage - Zhayolm Remnants for a 6 man boss run. Was trivially easy to keep my targets alive and hasted. We were BLU (me), THF, MNK, MNK, COR, and RDM. It was kind of a dry run to see how my BLU did in the healing/support role, which would free the RDM up to go BRD in future runs. With Battery Charge, Mirage Jubbah, Balharan's Ring, Auto-Refresh trait, and Sanction refresh, my MP never dropped below 600 (after Max MP was unlocked of course). I did get Evoker's Roll occasionally from the COR, but he was focused more on the melee, and of course I was splitting duties with the RDM, so if I was solo healer I'd probably would have had to be more conservative (I was wasting a lot of MP using Plenilune Embrace to buff the MNKs).
Against the boss, Shell IV (from the RDM) + Magus Roll w/ BLU in party = Discoid not being able to even break my Diamondhide. The RDM got so bored, she started meleeing* with her staff just to see if I could keep everyone alive, unparalyzed and hasted -- which I could. Of course, Discoid is pretty much the least dangerous chariot boss move, so I'm not sure how this would do in other settings.
I had Auto Refresh, Fast Cast, and Conserve MP set, as well as Wild Carrot, Magic Fruit, Plenilune Embrace, and Healing Breeze (a little duplication with what I got from /WHM, but BLU cures are a little more MP efficient), as well as Diamondhide and Animating Wail, with Regurgitation and Regeneration to fill in the last few points and give a minor MND boost (in retrospect I should have gone with the Frightful Roar version of Auto Refresh, but I wasn't sure how much time I would be spending near melee range, so I played it conservatively; in the future it'll be set).
So anyway, something fun and different to do, and gives me a chance to use BLU more.
*Yes, I know RDM doesn't have staff skill, and so did she; she just never remembers to bring a sword with her and was just doing it to be silly.
