We put together a team yesterday that got it done in 103 seconds, and that was the lowest we were able to get. But one of our mages only had around 90 dmg, so I think that was our weak link. I think ideal for this would be a team of all mages and rogues, with everyone having 120+ dps. No need to really have a tank in hauntlet.

I have a mage with 140 dps, so if you can find 2 others, we can give it a try.
