We came to pretty much the same conclusions https://forum.fracturedmmo.com/topic/15099/on-the-matter-of-economy-durability-masteries-gear-drops-imbuing
I'm confident that the devs understood that there is an issue in that area and will try new solutions.
By the way, I'm also in favor of limited uses for recipes, but unfortunately it doesn't math out. If we go by the concept that they should be a limited resource (and so just as many are dropped and just as many are lost), and you consider that someone changes gear every 2 weeks (6 or 7 items) then even assuming that a recipe has only 1 use, it would need to drop less than what it does now to have a real effect on the market. Since this is clearly not acceptable for many, I unfortunately think that recipes cannot be fixed.
