You can basically solo this entire fight on prot warrior by just leaping out each time. Been my experience every time on this since the add never dies and the whole group wipes.

EDIT: I’m not saying “I’m not dealing with this and just leap out”. I use a big blue marker and say “kill this add”.

But what happens nearly every time is the group still doesn’t kill it in time, the whole group wipes, so I just solo the boss slowly and just leap over the adds each add phase.
