As some of you may know, Version 1.3 will be out for MC on August 1st. I believe it will hurt economy servers. Some items that had high values, will now have low values, some items that had low values, will now have high values. Now that you get experience for mining, the market for enhcanted items is gonna go down. And now that books will have to be created with leather, they will be even higher priced than before (You will need 3 stacks of leather plus all the older materials to create one stack of bookshelves). Some stuff will be unaffected, like Wool, Dirt, Cobble, etc.
This is just what I believe, some of you may have other opinions, some of you may agree with me, all I ask is, What do you think?
