these equipments those of the priest that you see already exist on basic cataclysm, so what you see you can have it in your repack, for the others no there will be no patch for the SETs because it is not easy to do it and it takes a long time.

it is not only cosmetic, if you have watched the video well I also show you the items that I wear on the character, it is about a demotion of MOP items with its official ID for Cataclysm . For the rest of the Legion in SL it will only be cosmetics that can be used for event rewards and much more.
Here is a preview of upcoming content for Cataclysm.

this is correct for the very first patches, but the mount patches they will have to be apart, because they are no longer Morph but real mounts with spells to learn and then find them in your mount codex. If you want to mix them up then this is the result but I'm telling you now.
