All of the UNM materials have crashed hard in price, so it does effect the economy. Look at that person who spends a lot of RL money and time with all those mules just to do this campaign lol. I can't believe people would do that just for UNM, you realize how easy to kill most of these are? The only hard one is the PW2 and he can be beaten with a party of 6~8 well geared players. The drops aren't even the best anyway.
