So for ptr i only have 11.2.0 and thats live im trying to join the remix which is being a pain in me butt how 
should i trying updating my client? Or is the remix over?
Mop Remix is over, and Legion Remix isn’t out yet. I think it’s supposed to release in October, but I don’t know for sure.
I think the PTR for Legion Remix is up now — they just put a forum up for it.
