I would love the ability to fly without a mount. Be it with wings or with aether, I would love the ability to fly. Flight was one of my favorite things about DC Universe Online. It felt awesome to just take off and fly whenever I wanted. I don't see any reason why SE couldn't add unmounted flight to the game. It would add something else that would be fun to the game, and anytime anything is added that makes the game more fun is a plus in my book.

Also, for everyone complaining about "Wings everywhere!". Maybe SE could make it so that wings can only be displayed in areas where you can summon a mount. I think that may solve that problem for those that feel that wings in town would be something that they would not like to see.
