How Rare is the New Barbarian Crypt Tile Set?

[Val the Moofia Boss]

I've been running rifts but so far the new tile set hasn't popped yet. Same chance as all the other tilesets? Also, Blizzard should implement an option for us to ban/choose which tilesets we want to run, so at least we can play on the new ones for a while and appreciate the newness of it all.

I didn't even know we had a new tile set and I've probably run 500 rifts at minimum this season not counting Grift. So I guess I've never even seen it, which means it must be rare. I do see the sewer-y wood planks tile set regularly though, which was the last one I know about that they added.
