I could see it being useful in PvP against another BLM... maybe. I don't know. *shrug* That's what I originally thought it 'would' be used for when I first read the tooltip. It's clear that PvP was in mind when some abilities were made. For example, Rouse (SMN pet cooldown buff) wipes all CCs in addition to added damage -- and that was in the game long before PvP was introduced. The CC-wipe component of Rouse was absolutely useless until PvP.
