While this has already been posted on the dungeon forums, I would still like to be sure that attention is given to this.
With the new patch, the two chanters at the armseals will respawn after wipe, this has, however, had a bad side-effect. When a party wipes before actually reaching the two seals, and therefore not having killed the two chanters, the secondary group will spawn, and the two chanters will be gone. After this, the fractal will become a lot harder, and even after wiping they will not despawn to make place for the two original chanters. As proof I have tried it out on lvl 1, the pictures below show exactly what happens:
1-reach the seals- 2 chanters alive
2/3-jump down, triggering a full partywipe(check timer and log to confirm legitimacy)
4- run back up- 5 chanters alive, original 2 have dissapeared(timer shows 1 minute later, screenshots in log should confirm legitimacy)
It’s almost impossible to pug it 30+ now. Either you’re with a guild usual team in TS, or you’re in for having to quit if a single mistake is made. Even if it’s done the way it should be, but you get wiped.
