A small part of the reason the game economy is so skewed is people will sell something like this on the AH for 2k (Odin, and I'm sure other servers too...) when the NPC WILL give you over 4k... (as others have stated more than once...)
If we don't put the gil back into the economy by npcing things (the only way the game really gains gil into itself over-all) and SE keeps banning people for this that and the other, along with the RMT that we WANT BANNED, the prices of simple things like level 20 seer's gear is just going to keep rising. (The hilarious thing about this is, back when it was much harder to HQ it was a much more reasonable price... LULZ supply and demand baby!!!) <3
