I don't think this will hit Samus too hard, it just means we will have to recover much smarter. Start getting used to saving your double jump when you tether, practice getting max distance bomb jumps, try to reel in close enough that screw attack can't be ledge-hogged, and start practicing grapple boost heights for tether fail mix-ups. In fact this is pretty much perfect for our current tether limitations, it brings Samus' recovery directly in line with their design goal for recoveries.
I'm kind of wary about the extra lag on the ledgehop, but it's probably fine. Most of the time I just b-aired anyone trying to punish it, so this is most likely a positive change. Do hope we get something to compensate for a worse recovery though. Also bummed no Melee tethers but this is a good change overall.
