Thanks for details of the fight. I am used to playing tank. Done high level duties as tank. And have solved this before a while ago on another toon.

Oh. the problem of the completely changed skill bar.... Duh.

I'm not using Interject to stop the cast of "Sanctified Dark" of the mind flayer. I had recorded my fail and saw the cast.. Didn't know I had to stop it. Sigh..
Thanks.
