Link was unnessessarily nerfed. He's always been a little lacking in the power department.
Toon Link/young link, whoever, they maybe the same person but different items wouldnt hurt, they still throw bombs, boomerangs, and shoot arrows. He's had a ton of items and powers at his disposal throughout the Zelda series, Toonlink for example, summon a cyclone and carry him to where ever he wants. Why couldnt that have been a final smash? OH OH give him some of his mask powers, Down+b for young link turns him into his 3 majora forms, final smash being his Fierce deity form.
Gannon is still a Falcon clone, give him his damn sword and some of his powers over in the games, no reason to make him have a mix of both wizard and bruiser move.
Olimar is a walking failure.
Zelda/Shiek for whatever reason takes forever to transform, wtf?
Samus should be able to charge her down B and release a power bomb (a short range version of course it would be over powered otherwise).
Everything else: I agree with you guys.
