Yeah, took me a couple wipes to realize just what you're supposed to do. They really don't give you very much time at all to figure it out and then nail you with AoEs that kill you in 2 seconds flat. First, you might think to try and DPS the bubbles, but nope, can't target them. By the time you realize this, POP you're dead.

Second try, you leading them away from her and will probably get nailed by some other AoE that he continues to do and in the meantime, Tataru is following you around making things worse.

They needed some kind of indication of what exactly you're supposed to do there. Especially with it being as late into the fight as it is, having to re-do that whole portion again multiple times just to get back to that spot is annoying.
