I did say "eventually". And apparently what I meant was "in a few days". Honestly, nothing is really selling on Famfrit other than materia. Sure, things are listed at 3-5m but they only sell if priced under 2m for the most part, and even then a sale happens every day or two. So you're closer to 10m for an HQ left side after a week. It'll likely drop from there, though perhaps not as precipitously
This is also not "entry level raiding'. Buying NQ gear for 1/3-1/2 the price is totally viable for Gordias, Void Ark, etc. This is end-game raiding, and with even a few of these pieces at HQ you are set for essentially everything in the game that isn't Sephirot EX or Midas Savage. If someone really wanted a shortcut to the endgame, they can hit 60, find a gilseller, give them 50 bucks, and away they go. Is SE tacitly endorsing gilsellers? Probably. Does it give players more options that didn't exist before? Absolutely. Depending on who you ask, that may be a reasonable trade-off or not.
