Can you confirm Design: Rhinestone Sunglasses dropping properly on US servers? all confirmed drops are EU playersThe response from @WarcraftDevs:
Either those EU players got lucky, or they care more about sunglasses than US. The recipe drops all over the world.Now, I have no idea how to determine who's gotten the pattern and not, but I assume that OP does and that his source is valid for the purpose of this point. How would it be possible for there to be a world RNG drop that is found only by EU players if there's not an issue with it?
I cannot even fathom the logic behind "oh, EU must be farming those rares that might or might not still drop that pattern and the US is a bunch of slackers."
WTF, Blizz?
