We're seeing plenty of winged races being introduced, yet Aasimars all had their wings clipped, with older aasimar race classed characters getting to retain theirs.
Please bring them back, but maybe make it so there is a questline or FOIG basis and ways to make them return. That would be super cool!
Different requirements fulfilled could even lead to different types of wings or coloured wings being received (i.e bloodlines or paths/choices taken on these quests.
I get that they don't have them because their bloodline is considered 'diluted' but it would be nice to have a chance for them to have a way to 'gain' them through exclusive questlines, and give them a chance to grow; there's hardly anything for them as it stands and would make the race a lot more attractive to others too, from a strictly aesthetic perspective with no real mechanical benefit (Even though Fey'ri and Avariels are a thing). It would be super cool to have a thing to be able to work towards, and also keeps the limit of winged characters still somewhat down.
