Can confirm, I was able to run it yesterday without issue. If you load into Syrcus Tower and people start to panic, just reassure them that it is no longer bugged.
That being said, every once in a blue moon I run into encounters where folks with the frog buff keep it long enough to melt the safety ice that spawns second, so make sure the frogs don't get too overzealous freeing people.
You can also cheese it with resurrection, the raise invul blocks curtain call damage. But since everyone else is then dead you need a strategy to revive people afterwards.
Apparently Paladin's cover is enough to spare the life of a healer as well. So if you have a Paladin tank, one healer in that alliance can sac themselves while the other gets shielded through it and can quickly start bringing others back up.
Nice, that's good to know. Problem of course is can you coordinate that in alliance roulette instead of people just voting abandon as more people discover the problem.
