Congratulations to all those people and kins who worked on the Ost Dunhoth raid at the level 65 cap! However, now that the level cap has increased I won't be updating this thread again. Well done to all of those who attempted this challenge and here's the list of those groups that succeeded at various locks of the instance:
Aussieplayers (alliance raiding group), Council of Eriador, Dude Where's My Goat, Forbidden Few, Mount Doom Camping Trip, Prism (alliance raiding group), Rohirrim, There and Back Again, and Valacirca
I look forward to hearing about everyone's adventures in the new content. Good luck!
