Masquerade! Paper faces on parade. Masquerade!
I think you are missing the point to the complaints even after the Cache alteration. It has nothing to do with farming materials from the rest of the site. The fact remains that most formulas call for Cash items that are increasingly harder to obtain in one way or another. RIG fail items that are required in formulas outside of the RIG formulas are shooting up in price because you have many users wishing to craft said formulas in addition to the thinning probability of pulling said items from RIGs because of a larger item base as each new one appears monthly. Cash items that are no longer sold outside of what users already have are being destroyed to the point where the supply is being questioned tremendously and to even acquire one would force a user to spend hundreds of thousands or millions of gold for one. Imagine a formula that calls for multiples of those items or multiple formulas requiring one. There are still one-time grants listed in a few formulas. It took users pointing out the use of the Bunny Tail in two formulas that ultimately led to its change, though, what took its place was Bento Bunny, something that has never been sold again and may very well never be especially with the nonsense and headache surrounding that item's situation.
Gaia is doing nothing to alleviate that issue; no requirement alterations, no alternative paths, no reselling those items again, no formulas for those items that require components like that in the Cache and Case formulas as to not destroy more limited Cash items.
With the better odds in the Cache, you now have items disappearing from the site permanently faster than ever before as many more users try the feature out that never touched it before. I felt bad for sacrificing a Giant Syringe for my Giant Scalpel back in November. I spent just over 300k for it. Now tell me how many more users are going after crafting said item in addition to the Syringe's price tag in the Marketplace and its really low pull rate from RIGs that is only decreasing with each RIG released. Compare that scenario with limited Cash items like the Two Turtle Doves and Wedding Doves and Ribbons (for Dove Capelet. You need two of that crafted item for a Windy Gear and another if you want one just to wear). Please do not tell me you cannot see why users are up in arms over Alchemy still.
