For the last 2 nights I've been queued up with my Pugilist for Sastasha in the Duty Finder and nothing has happened.

I was on the duty finder for about 4 hours last night and 2 hours so far tonight and I don't understand how I'm supposed to do this instance if the Duty finder isn't working.

I've tried waiting outside Sastasha and asking for groups, but that hasn't worked either.

Is this just bugged? Is there any way for me to continue the story quests without being stuck here forever?
