As we all know here, GW2 is shaping up to be one kickass game. And ANet has always been open with how they are looking at other games for inspiration, not only in the MMO genre but all over. From FPS game lobbies to the Borderland-esque downed system.
So, given what we know of GW2 today, what feature(s) would you like ANet to "borrow" from another game?
Personally I would love to see a Charriocart minigame with unlockable cart skins.
