I was never able to do this until now, but I found a major problem with the changes to the damage attenuation system that is really bad for Urgent Quests. You can get the BP required to enter the boss without being within the level range of the boss, so it becomes possible to only be able to do 1 damage to the boss and hog a player slot in the UQ. This should not be possible, so this system still needs some work for UQs. I understand the player hogging a slot won't scale the Boss' HP up either, but why even allow this to happen?
This works for enemies in the open world because there are much more player slots, so a few under-leveled people in the map doesn't matter so much, but with the limited slots in UQs, it's really bad that someone could enter the UQ and not be able to actually do anything to the boss.
There really should have always just been a minimum level requirement for urgent quests so things like this couldn't happen. I understand the recent change to damage attenuation is because of people having issues with under leveled players trying to fight Gigantix, but this is a major issue for UQs that needs to be fixed as soon as possible.
I believe just imposing a level requirement for the Urgent Quests is probably the easiest solution for this problem.
