A piece of(non-legendary) BiS gear on wrath is 23 coins. MoP end game gear cost 24-33. The MoP server is so low on population and it seems the last thing it needs is everything costing more for end game items. I'm not sure if its done just because , technically the items are "better" (but in reality they are completely different xpacks and shouldn't scale with one another) or if because the server is so low on population that any transaction has to make up for the cost of running it. The server needs all the help it can get and just seems like a step in a good direction.

but, again, if this is done just to keep the server running, I get it.
