Oh no that is certainly not the case, it was not that flying mounts should fly. Because they can fly, they can fly everywhere currently, so at the moment I sure am hurtling down upon my enemies in current max level content. What will happen though is that it will be restricted for a short time in the future max level content.
What your case is, in the style of your reply: "When I purchase a mount I want it to fly and when I say fly I mean in max level content except instances and battlegrounds of course because reasons also not whilst levelling because reasons even though I use an RP excuse of a mount from Draenor forgetting how to fly as being ridiculous I arbitrarily forget about this during leveling also people who purchase this mount never purchase it just for the aesthetic appeal or for +1 to mount tally its purely about a Draenor mount being allowed in Draenor it does not matter that they can currently fly it they only want to fly in Draenor and so when they go to Draenor they wont be able to fly and will be angry because they purchased a mount purely for Draenor even when they could not go to Draenor and so they are bad men."
