You can thank the plat duping Gans, macro users, and Yantis type folks for the devaluation of pp in game.
When you can go to a banker and double your plat with with one mouse click, then you know there is something wrong. SOE didnt react quick enough, and the server economies are still feeling the effects.
When you can buy platinum with real cash, then things in game are going to become more expensive, since now this game is putting money in some player's pockets.
When you can buy a couple well flagged 65 toons and farm choice camps with them, then put the ornate or other drops on a bazaar mule and turn the pp profits into REAL CASH, then the prices are gonna go up.
In short, you can thank the folks who take this game WAY to seriously.
Cause the economy will only bear the prices that the consumers are willing to pay. I am not willing to pay that much for that stuff. Thus I wont pay 50k for a Lute of the Howler. I wont pay 500pp for a song when I know I can take 15 minutes and get it myself.
