Where to go after Stormheim?

So I've definitely missed a quest that links me to my next quest-able area which looks to be highmountain or val'sharah. I've just finished Stormheim (have achievement for all storyline quests complete) and am currently level 106, where do I go to get my flight paths to next area? I mean like I'm fully prepared to walk but that doesn't seem normal these days in WoW.
