I’ve thought about that too but it still seems useless when I realize that in order to get the full benefit I either have to put BS on a class that doesn’t use BS gear (like having it on my priest to send to my pally/warrior/DK in which case the character is wasting a profession to make gear for alts that will be replaced nearly immediately. Or I can put it on my warrior who is going to get gear drops and quest rewards along the way that are as good or better than BS gear.
It’s much better to just get two gathering professions and sell the mats or get a gathering prof to feed something like alchemy or jewlcrafting.
