It is unclear to me as to what you mean by "tier vi" and by "tier vii" Provisioning Crafting Writs. The Recipe Improvement passive has six Ranks, and the Recipe Quality passive has four ranks. So a "top level" Provisioning CW would require food with a Rank 6 Recipe, and Rank 2 quality (Fine).I see this is a long standing problem which just makes it more aggravating. Anyway I keep getting tier vi instead of tier vii writs. For a while, if I power cycled my PS4 and then deleted the application saved data for ESO before starting the game, then I would get a tier vii writ. Now even that doesn't work. Three months doing top level provisioning writs and I haven't received a single psijic ambrosia fragment ond have only had a couple of master writs. Argh.
