Using a spec like resto druid I am unable to beat this boss. I usually do Torghast on my resto spec since that is what Im most comfortable with, but even with a lot of anima powers, I am not able to out-dps her self heal, and her enrage stacks in the end beats me to a pulp. At least make it possible to vortex her.
Also, please allow to swap specs AFTER using the broker. The opertunity to change gear etc is removed after you engage the boss. Meaning I just wasted like 50 minutes getting to floor 6 finding this boss unbeatable by my current spec, and I cant do anytthing about it.
This is not really something that we can assist with here on the Customer Support forum, though it could be an idea to look through abilities that are available for you to potentially stun/interrupt the heal.
Otherwise you can also submit feedback regarding this or any other mechanics in game
