Definitely a major reason why I don't wear bronze armor unless I'm expecting to sit there and fight. I usually use troll armor. Also I find that while this happens pretty much all the time, the troll will only aggro if it's around anyways, and the adds that spawn in response to the noise you're marking are only like 3 basic greydwarves during the day. It's far worse at night, but you're obviously expected to try and avoid doing things at night when you can.

In my experience, though, there's not much point running from trolls unless you pop the speed buff or have terrain to slow them down. Though I've never had a problem outrunning them with eikthyr and not wearing bronze armor.
