It would be great to have an event themed for the season...
"Give someone a gift, get the same item for free!" in combination with "Limited-time mall availability of Dragon fang chest"
Every time a player gifts another player from the item mall, the gift giver will get the same item in his bag for free. This would be a great way for players to give something to their non-AP friends, at the same time getting something in return. Combined with the availability of a dragon fang chest with 20-30 fangs/chest in the item mall, big AP players can gift each other Dragon fangs, basically getting 2 chest for the price of 1.
I talked with my friends in-game and they all said they'd spend crazy gold if an event like this will happen. Which of course segues to the next exchange AP for gold event lol.
P.S. Dear Santa Memphis, if you like this idea and feel generous, all I want for Christmas is a Theseus approval and some vials and stones to make him grow
