Ganon really doesn't need any buffs at this point. There's a few luxuries he'd like to have (F6 jab, slightly longer grab range, and the grab on Dark Dive being stronger), but he's in a pretty good position as is. What he really needs is a few top tiers, especially Sheik, to get some changes/nerfs. He's a perfectly functional character with too many bad top tier matchups.
No i play multiples match against ganon. I made mistakes, not a lot but more than 3. I didn't die, and i never play heavy character.
He is supposed to hit like if you run into a truck, but the truck seems to be stoped.
He doesn't kill like he's supposed to, and how he's supposed to come back, or punish semi safe move on shield? He's Bair is weak, his ftilt and dtilt are weak, his fair need the hardest read and depending of your stage position you may live, his downB his useless most of the time and his side B doesn't guarented follow up on ton of character.
Same with link, you may be playing the character, but i see him as an opponent. What can you do if i come in your face and never let you space. What the purpose of his bomb, his bommerang, why his tilt are this slow? Why i feel like he has many weaknesses, that his strenghts don't balance.
When you look at ROB you see balance, when you look at Marcina and roy, or megaman you see a form of balance.
When you look at ganondorf and others you have the impression sakurai totally underate their strenghts or the crippleness of their weaknesses.
