Anyone else noticed that in the patch notes there was:
* Players no longer need to kill the final bosses in all four wings of this dungeon in order to teleport to Sapphiron. Teleportation orbs have been added to allow players access back and forth from Sapphiron's lair.
Does that mean you don't need to kill any of the bosses to get the Kel'Thuzad and Sapphiron achievements??? ???
