I know some method to prevent HQ has been asked for in the past, but as far as I know nothing has been implemented.

What I would ask is that Faded Crystals be given the ability to be used in synthesis. Basically any HQ item can be used with a Faded Crystal to get the NQ version.



Even as I write the request I know this won't happen as it would require adding a recipe for every HQ item in the game, yet we already have the Faded Crystal and it would be a good fit lore wise for it to function this way.
