If the pattern of "Fabled" zones continues Kunark should be next. While I love the idea of Fabled Veeshan's Peak I'm going to get a bit greedy here, why not do Fabled Kunark as a full blown expansion? Do 3 more EoF era zones for the summer Fabled, or Splitpaw/Mara adventure packs. Then make Fabled versions of every Kunark zone and a new quest line to repower and repurpose the Super Spire in Terran's Grasp to block a pending Shissar Invasion or something. And while the content devs are reworking the old zones to modern standards the art team could spend time to work on a new race, or a new set of armor, some amazing weapons, or more mounts. Even additional prestige housing.
Why not just skip the next expansion and Fable-ize every zone in the game from the beginning until say, DOF?
please also add FABLED crafting stations that can only craft lvl 100 items and if you fail it turns in to an aggro mob that wants to kill you just like in the old days when the forge killed you right
