so, if you were a night would you attack
A: the undead warrior with a broadsword
or B: the old lizard man weilding a stick shouting crazy words.

but i think it should be easier to attack mages aswell, just not very easy. and if you have ever faced falshe horror spam + skeleton spam it is far worse than one at a time (especially if he has relief casters) since the horrors can fly and hold you up until he drowns you in a horde of skele spammage death.
