Only if there's an option to hide other players wings.

One of the many reasons I left GW2 was because of the visual vomit it had become with wings and glow effects on characters. The game was aesthetically pleasing before all that. I really don't want FFXIV to become like GW2. x.x
So if it's always on, no thanks. If there's an option to turn them off on other characters, sure, have fun.
