Not sure if this is a bug or an intentional change, but the fight at the Temple of Zephyrs after the initial historian escort now has hordes of normal risen mobs spawning over and over that makes the event impossible for a group of even 10 people.
I’ve done this event fairly often and with good play you could complete it with a group of 5 competent people, but tonight we just got smashed by these respawning hordes.

Screenshot I took after we gave up, as you can see a group of 5 instantly started chasing me, and these things seem to run as fast or faster as a player does, so you can’t even really kite them.
And the priestess insta-resses the veterans that spawns them so there’s no way to keep their numbers down, making the whole thing just a huge clusterkitten.
