This really isn't appropriate dude. You should be able to talk about character design without insulting people like this. Cmon man.
As a Zelda main myself, I actually think that's hilarious and there's some truth to that. If he was saying it specifically about someone and I'm missing something, then tell me, but I honestly agree with it.
There is such a thing as bad character design, and I wouldn't put it over Nintendo to troll us. I kind of feel like, when Sakurai was making Zelda, he was like
"You know what's cool?! Fox's reflector, lets make a character that has something like that. You know what else would be cool?! A projectile that's controllable like Ness', but is more powerful. You know what's cool?! Teleporting, but lets not call it that. OMG, you know what's COOL?! What if there were [something about transform]. You know what's REALLY COOL?!?!!?!?!!?!?!?!? Let's give all this to the SAME CHARACTER?!?!?!?!? OMG WHO COULD DO THIS. Wait. We only have one girl. Let's make a new one and give it to her. But, oh, dammit, there are like zero female characters [doesn't think for more than a few seconds]. I was just at Nintendo conference about Zelda, so lets do that. I know, we can just give all of those powers to Zelda! Why? Because I'm Masahiro Sakurai, and I think it sounds like a good idea.
You know what sounds COOOL?!?! Let's make a character where the fastest move they have isn't a jab. I know, let's make it their down smash, and then they'll be OP, RIGHT?! Oh, and give them a lock like a jab does, but in their down tilt. Oh, wait. That tilt looks too bamf with all the cools specials and dsmash. I know, I'll just keep adding cool stuff and add lag, and that can be the character design. Despite that she's never been in battle, maybe female characters [something inspirational at the time...tear].
You know what would be COOL?!?! Let's have a character with OP aerials! Ones that give like over 20% damage. Well, we've been working on this girl, LETS DO IT Y'ALL...I'M ON A ROLLLOL!"
