Link is fine. Learn the counterplay, and just give tools to worse characters to better deal with projectiles. Everything from boomerang, pkfreeze, dins fire, laser, and fireball are immaculately designed and more characters should have the tools to deal with them through movement and other options. Like, would any of these be a problem for shiek, captain falcon, falco, fox, Marth, Peach, Jiggs? I doubt it. All of those characters have good tools to play around this stuff.
Thank god people recognizing Zelda for how strong she is. People--she's got great range, amazing power, low startup, and low cooldown on most of her attacks. She seems to get ommitted from top 10 by all of y'all because of the general assumption that Zelda must be bad. On top of that, her projectile game is fearsome and foces the opponent to do something or die at regular percents by being clipped by the blast radius of a bomb. Add in that recovery and you have a very strong character.
ZSS is way too low though, as is Peach. I'd probably switch Ness and ZSS, and move Jiggs down to Ganon level, move Ganon down to peach level, and move peach up to jiggs level.
