I'd say at the moment the problem is along the lines of

currently the generic chimerical felt set and hallowed chestnut accessories melded out with just the red scrip or favor weapon/offhand is more than enough to make literally everything with ease.

so with that your just making the specialized sets for future-proofing or glamour.
but then the question becomes "will they keep making the specialized sets easier and easier to get or add in a new better generic set by the time high stats are needed?"

it's just a bad spot, but the red scrip and favor weapons are very nice at the moment. It's just a matter of if you want to spend a lot of scrip per piece or very little scrip and then some money to materia them out
