don't let mobs pile up, kill them asap. kite troll in circles, slowly get swings in on everything else. take troll last, with bow if you don't like to melee it.

it doesn't happen often that you get truly gangbanged. and lol, wait for it to happen in swamp or mountains ;D

greydwarves/brutes you can WALK away from, they sure will follow tho.. just saying as it makes it really easy to dodge ther attacks while you regen some stamina.
