I can fully understand if you have somewhat close to a full LB3 or the boss is in its last few percent. But when there is 1, 2 or 3 left out of 8, 25-50%+ on the boss and there isnt even a LB1 available... just give it up and stop wasting everyone's time. You can do whatever the hell you want in your own FC run - but in a DF group, just wipe it so we can move on and progress through the dungeon.
