The thing is the stuff obtained from the old level 50 content is just for vanity now.

People don't like syncing down and loseing accses to their new ability's.

And unless they nerf stuff like T9 and 13 to hell people would at last have a legit reason to bail out from a roulette.

While I would love to get my minion from WOD I don't see this happaning. Unless they made it so you actually get exp at the end of it.
