Just cuz there cheap doesn't mean it's a good thing , if good items are cheap then it's hard to make Zeni . And considering most players I've seen have bad gear so lets say28 dex tmq7 jacket on tw is 200 and on hk is 20kk for example ( just a guess ) you still need to sell things like stones and armours to make that 20kk so if stones are like cheap it's gonna be hard to raise the 20kk
