Sorry, I don't know if this is a bug or it's intended because of the design of the realm (to be harder). I just saw that Proof of Demise quests (daily dungeon heroics) are available in Dalaran. They should award 2 emblems of valor instead of 2 emblems of heroism. Back in retail they gave 2 emblems of the current 25m raid tier.
Cheers and happy new year
