Sakurai said that if you worry about balance or fairness then you can't have unique characters, I said that you don't have to sacrifice unique characters like WFT and Villager (apparently) are to have a balanced game.
What you just said doesn't mean anything in any context.
Sakurai is KINDA right about that, though.
If you constantly worry about balance, keeping the game fair, etc, you can't really come up with any idea you want for a special move or for a character because first you have to say to yourself 'wait... that'll break the game' or 'no that's way too unfair,' so it technically limits what abilities you can give a character. It prevents a form of variety. I think if balance was his primary goal, we wouldn't have palutena's up smash.
I think his philosophy of 'create first, balance later' lets him make ridiculous abilities and then worry about toning them down later. I think that's really all he's saying.
If he don't really care about balance, then why did they buff some characters by making their moves better or revamped their move sets? Those happened, along with unique newcomers that we have been getting.
Yoshi, Pit, Charizard, Sheik, Zelda, Bowser, etc
He totally cares about balance, but he believes balance comes later. Make what you want first, balance it later!
