And you've just said everything I've said within these 250+ pages. There will be flight in Draenor. 6.1 will hit and we will wrap up some quest to unlock flight. But, in acknowledging that which is already written in stone, I also commented that Twitter and other "social media" or interviews are not solid evidence and are usually taken WAY out of context or read to be gospel. The only gospel truth I see is what makes it into the patch notes. Until 6.1 arrives and gives me Patch Notes which clearly state flying is NOT returning, I will sleep safe and sound knowing it will be back in 6.1.
A few hundred pages ago, I made a promise that if Flying never made it to Draenor, I would purchase the store mount of choice for all the people who called it, and then I would close both of my accounts and uninstall the game. I never make a bet I think I can't win.
