How about a pass all button instead of having to pass items individually, or maybe even the shock and horror of a selectable loot selection?
My last MMO had a system where there were 3 tiers of drops and you could automatically pass on set items.
tier 1 could be things like bat wings, gob masks etc.
teir 2 is crystals.
tier 3 is seals/pop items etc.
tier 4 is gear.
