I'm not sure where to post this, but whatever.
The eagle, or birds and flying in general, is a running theme in Assassins Creed games. I think it would be cool to be able to use a trained eagle as a ranged weapon/distraction in a future Assassins Creed game (I'm guessing that they will probably release more than just one more). Think about it, it could replace several game mechanics in a cool way. The bird would probably not just sit on your shoulder at all times, but you would whistle to call it (or something like that). Just a thought.
