Nah, the first boss is actually really easy.
I wiped about 7 times on him, then I changed one thing and now I storm through him. I don't even find him hard now and faceroll him.

The secret?

Add the debuff/curse to Healbot so that you know to instantly cleanse when it is cast. I insta remove the Righteous Beckoning (or whatever it is called) and don't have any problems. For movement, the second I see anything blue. I press forward for two seconds. Then dps again. I tank him from the beginning of the ledge.
