You need the lieutenant commander title you get from 1800 RBG. Then you can transmog the old sets.
You can mog them, you just need 1.8k RBG rating on a class that can equip what you want to mog. So if you get 1.8k on a single priest, then all priests on your account can use both faction's mog and warriors on your account can mog the staff if they want to. It's a weird system but hey.
You can also use them if you got one of the old PVP ranks, I think rank 10+
