How is Everyone Managing Delirium Pinnacle Encounter?

I have yet to clear one Delerium Pinnacle event and I am level 95 SSF. I don't know if I am unlucky with the modifiers on the rares and bosses or what. Stage 11 had the boss with the invincibility aura and the healing aura and a rare with the mana drain aura. Any damage I would do would get healed and the mobs were invincible 90% of the time.

Is anyone having success on that encounter?
