I tried to search for this one, but nothing on layered gear came up.

Pretty cut and dry, but I really like that the game is pretty good at handing out SG, more than enough to get the gold tier for the mission pass and pay for the Hot Deals. I was just curious if the Layered Sets have ever released in this fashion as well ie, over on the JP servers?

Mission Pass is not in the JPN server at all; all cosmetic items in the current Mission Pass are from the first year of AC and FUN scratches.
