Just yesterday I gave my friend a Troika for a low price. I would have rathered it be for free, but hw wouldn't have it. I realize that it is definitely possible to gift things to other members, but maybe we could develop a seasonal gifting system. We could have a tree just next to the auction house and you could approach it to leave or receive a gift. The tree would have some sort of indication present if you had a gift waiting for you and a special animation when opening a gift.

It seems like a cool idea to me and I'd love to see what the game designers could do with it.
