As much as I love running Ascension Chamber, the Mordenkainen Disjunction bug has scared away most of the regulars in my crew.
Please Eladrin, or whoever is responsible for this, shut down Ascension Chamber and fix this bug as soon as you can. For many characters, the Litany of the Dead represents consolidation of the trinket slot, and is part of many builds that include the +1 profane bonus as part of the final stats.
Please fix it guys. I know a lot of people that really enjoy the level of skill, coordination and determination required to beat this raid.
