I definitely don't want Loot Master especially with the DF changing the party leader & the possibility of someone in a PUG abusing it. The ability to trade drops dropped within an instance to other players within the instance might be nice. Even normally untradable stuff.

What I really would like is to be able to downgrade my roll from a Need -> Greed or Greed -> Pass before the timer counts down. I have accidently Needed stuff someone else could use that I didn't actually want and would like a mechanism to change my roll.
