This is a good point. Also to note, most of the time when they get to the double / triple flare stage of rotation, the mobs is really dang close to death, if one happens to peel off, it's fine, it will be dead soon anyway. In this situation as BLM I put up my ward and burn the bastard that came to say hi to me to tha ground. As PLD when this happens, I usually stun it, if it's up, to give the BLM some time to do so.

Quelling is for big pack burns, and bursts on bosses and to be used with raging when possible. Really that's that.
