My main complaint is that playfield instances seem to be filling up a lot faster than during the 5th anniversary events. Getting into the instance in which cultists have been reported before it fills up seems to be much harder now than it was back then. Either there are more players now, or the maximum number of players per instance has been decreased. In the combat logs so far I saw only up to 70-ish players at the same time.
And as always, what's the use of having all this nice new social armor if there is no space to store it... We need more storage space, or some easy way of getting social armor back after deleting it (e.g. by being shifted to /claims or something like that).
Edited to add: I didn't start this thread and certainly didn't pick the title - I have no idea what happened here but it seems that someone deleted the first 5 or so posts in the thread. I don't think the world boss idea is boring, but the number of players allowed per instance should be increased and the respawn time reduced somewhat.
