Not that we were likely to do that with just the 4 of us on 25 man.
The whole thing was made slightly more difficult because the weekly with the rare, Archritualist Kelada, had popped up and he was right outside that door. It just meant we had to kill him with every reset.
With the four of us it was easier, as two would go in and the other two would summon them out. Sars came along late but he got his done pretty easily!
So the cool pop culture reference for that is that all those Ritualists are named after monsters in Dr Who!

So here is the mount, Armored Skyscreamer. It's not a very attractive mount, is it? Take a good look because it's unlikely I am ever going to see it again!
