that's probably the only situation where it's even remotely decent. it's far more common to have a horde pack of anarchs than mallet lords (i think i've only ever seen one), and with faster animations, dodge is a liability.
MLs are probably the only pack where dodge is appreciated, and even then, they attack so slow that with DS or good enough mitigation, there's no reason to fear them.
also, dodging the first just sets you up for getting hit by the next 2-4.
