Dunno, I think the april fool's joke was a bit too far. Obviously it was taken to the extreme, but items do need to be hard to get to a certain degree, I'll agree with Redblade on that. I don't think Cadiro and the latest trade improvements ruined the game, but if they added a functional auction house where you could buy and sell items independently of human interaction at all...I don't know. We would probably see ten times over the amount of items for sale that there are right now and anything below tier 1 rarity would become essentially free.
They plan on adding the ability to trade without needing to be in the same instance, I think that will be as far as trade improvements need to go.
