Why less epic? I want it to be epic! Make it play a looong awesome cinematic every time you attack a player with Wings! Also, when angels or archangels attack.
Still, I don't know if the whole idea of Wings fits the theme of
... it 'sounds like' giving you freedom of movement (flight) but the actual effect is that a lot of creatures are stopped, which seems not very air-ish.
I have an idea for an air shield that would be equally powerful and game-changing (well, almost), but would fit the theme much better. Sadly I don't have time to make a thread about it right now
