I had a similar experience in Sastasha the other day. Me as dragoon (single-target only at that stage) and paired with a new thaumaturge who didn't seem to have worked out AoE spells yet, but the tank kept doing weird pulls that were just unhelpful as a result - like picking up the two guards in front of the Waverider Gate *before* fighting the two in front of the Captain's Quarters, so we had all four of them at once. Then dragged the big guy inside that room out to the entrance instead of just fighting him in place like every other run ever.
They weren't holding enmity all that well either, so I had to watch out for enemies that broke away and went after the healer.
At the final boss they put 'ignore' marks on all the water grates - unusual but okay, I get it - and pulled the boss right up into the corner.... but how does that bit help? We're further from some grates but closer to others, and it just feels like doing stuff that potentially confuses other players for very little benefit. Maybe a few seconds saved?
