To me, this was a much wanted change, Calamity and Thorium both made pre-hm wings that are funnily both post skeletron champion wings obtained from the buried champion and can only be fought after skeletron has been defeated, though the flight armor gives wings as a set bonus, they aren't true wings and the skyline wings require bones, but either way, with all the changes made to Terraria it just makes sense to have pre-hm wings, as I never and I mean never used the lucky horseshoe because it just felt so underpowered compared to just using a bottle instead. I don't think that they need to be changed as they are easily replaced by rocket boots later on and it just makes progression feel a lot smoother to me, sure gliding is very helpful but you can't nerf the glide speed because it matches up with your running speed, so even if they have a flight speed of 15mph, any running boots boosts it up to 30mph, and the flight time isn't even half a second so it just makes sense to me to have these in pre-hm, they aren't super op, they aren't super trash, they're a good accessory that just made sense to obtain in sky islands, i mean they're literally called sky islands, Starfury is a sword forged with the fury of the heavens and is extremely useful sword that is needed for Zenith, and the shiny red balloon, a balloon that requires helium to float and allows you to jump higher (I don't really get this one but it kinda makes sense in a way). and then lucky horseshoe. it was a lucky horseshoe that prevented fall damage and it didn't make sense that it somehow ended up in a SKY ISLAND. it makes more sense for straight up WINGS to replace a horseshoe the belongs on a GROUNDED creature
