I'd be surprised if this hadn't been suggested before, but I think it would be nice if TRs could elect to turn off their wings. I'd be happy with either a static decision during the TR character creation screen, or alternatively dynamically whenever they felt like it throughout the game.
At times, other players assume certain things about TR characters that may not be true. Being a TR can create the expectation of being uber by virtue of having wings. It'd be nice to be able to dodge that short of a character inspection.
Similarly, expectations of 'advice giving / game mechanic explanations' or 'build explanations' can be frustrating if you're not in the mood.
On a macro level, I think the vet / newbie divide would also be lessened by the presence of fewer wings around names running about the harbor and marketplace.
I appreciate an inspection of the character will still show Hero / Legend. No biggie, and that's fine; the visual disappearance of wings would still cut down on the above problems. Making it optional removes the downside for those players that do love the wings.
I would genuinely use this option 100% of the time, and for others that wouldn't, no harm no foul.
