Arguments of practicality over aesthetics aside, why wings? This is probably the oldest request in the history of requests for MMOs, so much so that some company decided 'eff it' and made a game where everyone gets wings after a certain level (Aion). I never understood the draw, myself. I mean, really, if they do add wings to a set of armor they won't be functional, probably won't even animate, and will more hinder than help as the game has enough crap that likes to block the camera as is. Heaven forbid you should find yourself having to get against a wall or barrier. That's probably why they took the cape off Odin's armor for players.
