As long as we are talking about bosses, how do other monks handle Chimera? I have no problems until sub-25% when the floor goes wild.

We tank the boss at the NW corner of the battlefield, so I can't stand behind it (exposes me to sand traps) or stand at the left or right flank (exposed to breath). If I use guerrilla tactics, the traps catch me--there simply isn't enough time to escape, even when I move in just as the trap fires and hug the wall on the way there and back.

The current strategy is lay down and die as soon as possible in order to switch to ARC or BLM, but that feels a little defeatist to me.
