The zone in which you do the Forge of Aeons scenario (the questline to unlock Lighforged Draenei) has some invisible walls around it, but there are a few branches which you can jump with DH or probably also Heroic Leap with warrior (haven't tried that).
It's basically just a cut-out from WoD's Tanaan Jungle zone - the area where you do the questline with T'paartos is a copy of Zorammarsh, while out of the quest-zone borders there is the entire Temple of Sha'naar and the 'transition' from Tanaan to Talador with the mushrooms. There are also some cat-people houses from Fang'rila. Hope you enjoy.
