I don't recall if the quest is available in normal or if it'd work in norm, but just a few minutes ago my group made the unexpected discovery that if everyone runs PAST bladefist to the mini-boss behind him ht will reset and you'll find yourself standing next to the miniboss executioner that you have to kill with bladefist standing back in the center where he spawns.
Our tank wanted to do both the mini boss and bladefist at once so he ran back and BF reset.
I tried to get a screen shot, but this kind of thing is kind of difficult to SS since it covers so much area and the room is symetrical.
Edit
Here's the screenshot I managed to take but it's not the best because the tank was impatient juts wanting to get on with the run and ran in, no less you can see people (not me) talking about how he reset, and you can see people running back from behind to chase our tank. I doubt my guildies would have taken kindly to my announcing a need to wait for SS for a web site like this lol.
