Fuck no. We had Grace's DK there and Beafe healing on his priest. We activated the trophy room adds then started the gauntlet so the adds and boss from the first room attacked while we were still progressing in Skadi's gauntlet. It's fucking awesome if you can pull it off. (We did). You better get ready Sunder, cuz you're going to be tanking it to keep your title of "best tank."
Go Heresy Red Team! A new one for the record books!
