No, is not working. I had the same issue. Doing the 3 man instance will not solve problem. The epic quest is to destroy the relic and after that to kill Ergoth. Is an bug since Rohan was launched. When u finish aligning the mirrors, ask for an GM and stay there. Either the webs will not open, either the boss is not there, those are the 2 bugs possible. Anyway, the GM can help you and report as bug again.
