One thing I have found, however slow and tedious, is to find a place to hide, pop out & charm a monster from a distance. Then the monsters will target him and vice versa. Rinse and repeat a few times until a large group is manageable. Playing a warrior mage, and like I said, it's slow going sometimes, but I stay alive longer. The downside, I think, is no XP if you aren't the one actually killing the mobs.
