Well I've been thinking about Link in relation to tiers recently, and this is what I've come up with. I guess you could call this my first draft. I am willing to hear out counter arguments or whatever, but your reasoning behind it, and possibly game footage to accompany your argument would be appreciated.
Keep in mind that I am aware my list is probably inaccurate, and goes in no particular order. This is going off of my experiences, and based on footage I have seen. This is also based on no characters having customs and miis having the 1111 sets, because I simply don't have the time to learn every character's custom sets in order to even make a semi-accurate guess. This is also based off of 3 stock matches, because rage in two stock majorly influences tiers.
Link is better than these characters:
Little Mac, Wii Fit Trainer, DDD, Kirby, Olimar, Pit, Dark Pit, Charizard, Lucario, Robin, Marth, Lucina, Bowser, Bowser Jr, Falco, Palutena, Ike, Dr. Mario, Ganondorf, Mr. Game & Watch, Mii Swordsman
Link is even/unknown with these characters:
Mewtwo, Samus, Gay, Peach, Mii Blaster, Wario, Mii Brawler, Duck Hunt, Donkey Kong
Link is worse than these characters:
Shiek, Diddy Kong, Sonic, Luigi, Captain Falcon, Pac Man, Meta Knight, Shulk, Ness, Rob, Mario, Jigglypuff, Greninja, Zero Suit Samus, Yoshi, Pikachu, Fox, Mega Man, Rosalina & Luma
Characters that Link is worse than, but has a favorable->practically even MU with:
Sonic, Luigi, Captain Falcon, Pac Man, Zero Suit Samus, Pikachu, Shulk, Rosalina & Luma
Characters that Link is better than, but has an unfavorable->practically even MU with:
Wii Fit Trainer, Ike, Marth, Mr. Game & Watch, Pit, Kirby
