I'll use it once in a blue moon in order to prevent a wide 35k AoE from going off where it would have restricted myself, the tank, and the other melee from AoEing casting mobs within the AoE's radius.
...I think that's it, though, apart from the same uses its old version had (save that I can also deal with the few damage-absorption buff casts which were previously immune to removal), but even rarer in that it's less likely that I'll be able to align the stun by chance than be able to align the buff removal before it's not worth the damage cost.
