I am almost Veteran lvl 4 and made 50 provisioning a long time ago, i am having a hard time finding recipe's and the mats for the ones i have found in the areas i am exploring, any boxes or barrels i do find unopened contain the level appropriate mats for the zone's original adventurers
Veteran lvl 1 glenumbra was thin broth's and the like, these were the items i used to create level 1 and 5 foods. that is when you can find an unopened barrel, because everyone and his monkey's uncle is auto looting these on the off chance they find a motif. No idea what they do with the food stuff they find, it's never on my guild store so I can only assume it gets destroyed when the bags are full.
as for recipe's I found a V5 level recipe when i was lvl 19 in a barrel in deshaan, and another somewhere in my early 40's in the Rift, in the veteran area's i have found 1 veteran 1 food recipe (same one multiple times) and it requires imperial flour i think it is, which i have not found at all.
Am i just really unlucky or are these mats unavailible ?
In beta the boxes i opened gave me level specific loot regardless of where i was, and somewhere when the game went live they changed that to be zone specific, this seems to have carried over to veteran zones as a result.
Also I think that the removal of motif books from barrels and adding them to the loot table would go a long way towards a fix too, just don't add it to public dungeon mini boss loot, since the gold farmers are making those not even worth the time to visit.
