Who designed this quest? Who thought it was a good idea to keep spamming aoe and aoe and aoe?

I tried this on my monk and I can't do it. I've tried three times, I get to the phase where you need to bring him down to 95 % and I just can't do it. At some point there's aoe everywhere and I die.

I am shaking doing this quest and now I just don't wanna do it anymore, because I keep failing. I can only do it if they nerf it. Even my smn, a different character, needed several times to get it done.

If anyone has any advice on how to clear this as a monk, please share.
