Legendary cloak is 1-90 when WoD is released, Val'anyr, Hammer of Ancient Kings is 1-80 and Sulfuras, Hand of Ragnaros is 1-60, and so on.
Also please implement dyes so, so we can get access to old lfr variations of gear (Dragon Soul now and MoP when WoD is released) or have new hc (or normal/flex/valor) gear match current outfit. Perhaps we even can get access to existing but unused color variations of gear. Transmogrification has done much more for the game than I thought it would and is really awesome. Perhaps even make transmogrification cheaper so we change more often.
