I have done every quest for BFA mining YEARS ago and for some reason my skill shows 1 star and my gathering rate is just pitiful, was mining nerfed?
Nope. My 2 and 3 stars are still there. I have a lot of alts who didn’t actually finish getting up their Legion/BFA gathering upgrades (and some I never earned on any alt), but those who got upgrades still have them.
My mining toons (of which I have 3) all still have their star ranks.
