That a means of removing all the Materia from an item exists in game does not invalidate my point : that without having known what the craft/control req's were going to be, it is entirely possible that people, months ago, used T4 Materia and got too much craft, not enough control, in their melds.

That circumstance is a failed attempt at the future-proofing someone was scoffing at someone else for not having done.
