I agree with this, of course. Even said so in my original post.
Having crafted in 1.0, and again in 2.0, and again in 3.0, I can tell you that the current wall is nothing like what was present at any stage of the game, and reflects a specific change in design philosophy. Let me break it down for you:
In 1.0, almost everything was crafted. The economy was player driven, often to impractical extremes. It drove a huge number of players from the game.
In 2.0, as you well know, crafted gear for PVE progression was rotated in, in a controlled manner. There was usually a tier of crafted gear from a few classes at a time that was viable (and occasionally optimal) to wear in the cutting edge raids. I made a great deal of gil at the launch of ARR on astral rings and the like - properly melded, these were of tremendous use in pushing the first coil.
3.0 is where things take an abrupt and unprecedented plunge. There was no viable crafted gear for PVE progression at launch, and the "crafting patch" has introduced a limited selection of ilvl 180 gear with a ton of limitations that you will almost never see on another player, not only for reasons of extreme scarcity due to the scrip system we all know and loathe, but because of the "death" of materia. Grade 5 materia cannot be gotten in quantities necessary for crafted i180 to provide an alternative to i190 and i200 stuff. They don't want Grade 5 materia accessible to players until after its window of usefulness in cutting edge raid content has passed.
To top it off, SE specifically excluded 180 combat jewelry because they knew it would be flexible enough to be useful in raids.
If all of that doesn't clue you in on the change in design philosophy, SE has flat out stated that they were displeased with the role crafted equipment played in accelerating content clearing in ARR. If you find that unbelievable, I can find the statement for you, with a bit of digging.
Finally, it takes three days to spin up a Tier III FC buff. Three days for twenty-four hours. These won't be a huge benefit unless they allow us to install three aetherial wheel tables in our homes. And even then, consider how many FC credits we'll be burning on fuel to reach the far islands necessary to produce these buffs. It's 10+ units of fuel on these trips. I'd be surprised if it wasn't a net loss in terms of credits.
