My guild just downed Nightbane for the first time (with 9 people!) on an empty server. Many are quitting the game because of the state of the server and (AcTiViSiOn)-Blizzard in general.
Soloing outdated and obsolete raid content is becoming arduous but I'm still able to solo Return of Karazhan and kill Nightbane. - Imgur
