It’s been a while, but I heard a rumor some years ago that patterns will drop only for those who have professions like Tailoring Patterns only drop for Tailors. But I don’t know if this is true, can anyone verify this? I’m trying to farm some recipes that don’t bind from Auchnei Crypts & Shadow Labs, both drop tailoring patterns, but I run in on my Demon Hunter, a leathworker.
short answer is some do, some dont
your best bet would be looking up the recipe on wowhead and seeing what the comments on there have to say.
I’ve had recipie drops for all professions except engineering on all my alts. My engineer main has had several blacksmithing and two alchemy ones drop. So, yes and not ser to profession of the character.
