Maybe I'm in the minority here, but in fights with high uptime and especially either with no ballad or if I was having to raise. I find myself running out of MP if I'm doing a good job of keeping the Malefics going. Seiryu was a good example where on many occasion I'd throw an Ewer on myself if it was going to align with my extended shroud. Doing that was borderline essential in pugs if I still wanted to aim for decent DPS output.
Bole? Meh, it was a fundamental part of my strategy in A12s (The latter part of the add phase) to the point where I'd actually save it for one of the tanks. I've never really found anywhere else where it was as impactful though.
