Uhh, they're getting rid of the ability to buy them from vendors, but people who still have their WH/EWH sets will be able to keep theirs. The new sets are specifically for level 55. The old sets won't be buyable anymore, but they're not being deleted from the game.
I wonder how many just won't buy the expansion to remain a level 50 twink forever?
that twink is gimped, because they nerfed all the stats for level 50 even with bolstering the stats are much worse then now on live. You will be slaughtered most likely from people with greens/blues from makeb.
