To echo what most others have said, BS is mostly useless now.
The gear that people actually want is usually dependent on a ridiculous amount of mats of which many can only be gotten from raids. It’s slow, very wasteful, and people can usually get better from just raiding themselves.
I’m really disappointed in Blizzard making the profession so useless and wasteful. In Legion we at least had a niche in that we could create legendaries and a mount, but now? Now we just produce overpriced gear that takes forever to craft and is almost impossible to make any measure of profit from.
