While I'm glad recoveries are being nerfed so the general speed of the game will be drastically sped up, I'm also a bit sad. It's almost guaranteed that my main Link is going to be hit with a recovery nerf since he has crazy recovery options.
I seriously doubt they're going to hit any characters with already bad recoveries as it makes no sense and are instead are going to hit the best recovery characters with a load of options like Mario, Link and maybe Ivysaur. Those are just a few I know with really good recoveries on the top of my head.
Woah... what? Ivysaur only option is a tether we all know how force jumps can be punished. Yeah, it's long reaching but it's predictable. I also believe dair only slows momentum after two uses. See her on the average to weaker side of recoveries only because her up b is so long.
I don't see Link getting touched either. A lot of his tricks are needed for him to not be low tier. Meta Knight doesn't have to glide to recover, but he can. Link nearly has to AGT to come back from horizontal trajectories.
I agree that Mario is going to get looked at for a nerf but not as much as people who can glide like Meta Knight, Pit, and Charizard or characters like Mewtwo and Diddy Kong. Samus has amazing recovery, too, and between bomb jump stalls, a solid up b, floatyness and great air control and one of the longest tethers in the game I amaze no one complains about her. Hell charge shot not only pushes you in the opposite direction but stalls your drop speed.
