I agree that clearing events are more fun but I don’t remember them working much better.
I tried organizing small UDLs at the time when there was no HP scaling (so in a group with 5 warriors you could just miss the boss) and maybe 3 people were interested of the whole mob sitting in USE2.
Also see:
Parasites are the best dungeon to clear for fame, pots, and safety, but it just doesn’t happen, someone rushes and everybody else TPs to boss room, and you get a nice surprise from behind when a maw gets dragged in. Clearing doesn’t even take long if the whole group plays.
I ended up deciding to nexus/ breaking the chain so often is not even funny.
