It's annoying as all crap that someone opens a treasure box at the end of a normal raid roulette and leaves, forcing you to receive every useless item in your inventory.
Or 4-player dungeons where you don't want any of the gear and it can still fall into your hands.
Or Alliance raids where everyone leaves and you're stuck with the rest.
PLEASE ALLOW PASS ON ALL LOOT WHEN WE START A DUNGEON.
