I decided to give it a look when I got home from work.
I beat it in Legion 3iLev under the recommended iLev of the time. (Many attempts were made of course). I had learned a lot about Holy priest doing it too. I’d argue it made me a bit better.
I was however not prepared for my cc to last 5s instead of its duration like it did in Legion, nor was I prepared for this mage to two shot every NPC they targeted.
It was quite comical XD
