I know it's practically impossible for anyone to answer, but do you think minor wiz oil will ever be better than +3 int again?
If not, I won't bother stockpiling it anymore.
My druid has kept mining and enchanting as prof for about 8 months b/c of my insane fear of scarcity.
As you said, we obviously have no way of knowing whether they'll ever change Minor Wizard Oil again.
Regardless, you would be a lot better off with Alchemy + Herbalism for the +14 intellect you get from Elixir of Wisdom with the Mixology perk. When you start running low on your stockpiled Oils, you can always drop Herbalism temporarily (keeping Alchemy for any rare recipes you might have) and make some more - leveling Enchanting to 45 is pretty easy and Strange Dust isn't hard to come by.
