I think a bit of inflation would help the economies at this point rather than hurt it. Nearly nothing has much value anymore and the little value it has is because not many people spend the time to farm said items.The problem is the people who would use said items actually mostly farm it themselves anyway so thus the goods with value never sell. So because they never sell, they'll keep dropping in value till someone actually feels its justified to buy them.

Using Aldgoat leather as an example. The only use this item has is to crafters. Crafters won't buy it in bulk because it costs more for the leather than the finished products. So players tend to buy only what they need at the cheapest possible price to HQ the items they are working on. It causes the market system of Supply and Demand to break down since the supply will quickly beat out the demand; and the market will run down the price to nothing.
When 2.2 hits it'll stimulate the economy for about a second; then quickly everything will plummet in price as the general population can not AFFORD to buy the goods. Once the 20% wealthy buy what they need then there is no one to sell to anymore and the prices will get ground to dust.
