Yes, they're Ashran-only items.

At first I thought that Rogue's had a bad item, until I got to see what they're able to pickpocket. Now Shaman seem to replace that status, and I'm not really sure what benefit there is to a shorter cooldown on Reincarnation. If it brought you back to full health and mana, I'd understand, but as it stands now you're still a free kill once you stand back up.
