Is this Normal?

Since this seems like the most appropriate thread for this at this time, has anyone done Chaos RA recently? While I was browsing the FM today, I saw a shop which I know, well, I assume, to be maintained by a hacker, given their shop content in the past, and it had some RA equips. It could be from the last gacha box or marvel, or something, but I still find it suspicious. It'd be a hell of a lot easier to tell if they fixed stat variance. I've also heard that Evo Empress+Instructors are dropping their items now as well, but so far I haven't seen it for myself, other than the recent spike in the supply of shoulders, and I'm hesistant to waste more coins on Evo Empress.
