The only thing that really went up noticeably on my server after the opening of the badge Vendor was
[Thick Clefthoof Leather](3g50 before, 11g now). Come to think about it, it might also be related to a lot of people bringing up leather working maybe, that leather type being the key material to later skill ups and an ingredient to the very much desired drums. Add that to the fact that with all the new leg armors that are needed for the items from the badge vendor.
I monitored all of the primals, including primal nether, they all stayed pretty much stable.
