Yeah, the combat doesn't have the death-match FPS feel but your movement (or lack thereof) seems to have quiet a bearing on the turnout.

I've engaged multiples a number of times and found my butt being handed to me in short order if I don't work on strafing or keeping my back away from the mobs. I find that when I attack one and if another aggro's, that "add" tries real hard to stay at your back where as the original target tends to stay at your front. I get a strong impression of a team-work feel on the part of the mobs AI.

So under similar situations I've died very quickly when I put little effort forth and then learned to strafe and flank at the same time trying to target the head/torso of the mobs as they duck and weave.

So while it may not be a rush it's still engrossing (unless your opponent is trivial).
