Have you considered you get undercut so hard because you overprice even the smallest of things?
Vanya was 5 - 10 million at release.
Arachne gear is 5 - 10 million at 2.4 release.
people charging 100 - 200k for an i55 NIN wep JUST because its required for NIN Relics.

I hate everyone who plies the MBs for this reason.
