You got it all wrong. The WHM Holying and burning their MP does not need you to recover it, they can do it by themselves with SoS and between the pulls. I've wondered why BRDs try to ballad me instead of swiftsong and requiem, but I guess you just answered my question: they're freaking out. No WHM who knows what they're doing and are well geared (item level 90+) should need ballad in any of the level 50 dungeons, ever.

This person got it right:

Yes, I tend to use Holy a lot, and that's because it can do 1100 damage on each target it hits on crit. 700-800 on a normal hit. With Foe's Requiem it does even more than that! Most DPS i get the pleasure of being DF'd with are below i95 and aren't pushing the dps I'm doing on large pulls. As long as the WHM isn't begging for Ballad each pull and slowing down the run asking for mp breaks I feel its perfectly fine.
