More flexibility with dungeon gear loots: Leader loot & Player trade

[zirkaloy]

• a Leader Loot (Master Loot) setting available for pre-made groups

Yes, for obvious reasons, some that you have stated.

• a player-to-player trade allowance within the dungeon

No, because this would push people to group up (8 ppl) in a 24m raid, all need on an item and decide to give all the loots to their friends.
Do you remember what happened with tokens when LFR came out?
