Anet sets maximum prices on traders (really this is all it would take)
+add more crafter weapons(maybe some better models...!)
+increase good drops just a little
don't see how that well help much....
the gold between those who made effrot to gain (farmers) and the casual player is still going to be an ever increasing gap. As more people gain more money with no where to spend, it will just drive up the price of what ever drops.
I say need to add some "distraction" to get people off farming items.
i really wouldnt know, but the economy seems to be in a relativly good place at the moment. Except for people who sell krytan axes for like 30 million gold. O well, i could be wrong.
