Haha we just did this quest for a guildie last night and he was harassing everybody to loot also. I feel the pain, I’ve skinned in MC before.
A lot of people don’t realize you can right-click your portrait, select Pass on Loot, and change it to either Yes or No.
Either way, while I don’t really remember the bracers, I very much remember the same issue getting Ogre Beads. On the upside, dungeon are fun and UBRS is a great one that folks run a lot, so running it multiple times shouldn’t be too hard. They’ll drop eventually!
Good luck to you
