I had GE all to myself as an 89 monk just farming some tribute items, so I was running around looking for named, and mostly ignoring the mobs beating on me. At one point I noticed the cumulative damage was enough to be worth firing off my 25% mend, so I did and went back to navigating. Then I noticed I was back down to half damage really soon, and was still going down. I'd picked up the entire room full of minions, not realising there was a 2.0 epic fight buried down that passage!
Feign Death FTW. :-)
