Kay, I really feel like I have to say something about this.
Why do the Kirby characters get so many jumps?
Because that's exactly how they actually move in their own games. There's not much to say beyond that, in most Kirby games, you get
infinite freaking jumps, it's just a part of the series and correctly representing that feature was obviously important to keep the characters accurate. Charizard? He's kind of never been on a game where you have direct control over him. I do agree that giving such a terrible air mobility to a flying-type Pokémon is kind of weird, but that's kind of just one character. Also, Jigglypuff may "not" get a recovery in the conventional sense, but her horizontal movement is so freaking ridiculous that she's recover pretty much 100% of the times you don't leave her way below the stage. At that point, she barely even needs a movement-based up+B.
Jigglypuff does not have a bad recovery under any standards.
And now let's talk about Pit.
You know what's funny about Pit?
He's not Sakurai's character.
Sakurai had literally nothing to do with Pit's creation, so accussing him of bias when it comes to giving him a good recovery is laughable at best. Yes, he revived the franchise when he worked on Kid Icarus Uprising. But he did so
years after Pit was added into Smash Bros. When Pit was given four jumps in Smash, Sakurai had never touched the character before, so where exactly would the bias come from? Other than the new moves given to him in Smash 4, anything that Pit does in Smash has nothing to do with Sakurai working with the character because that actually happened
after Pit's inclusion. What makes this even worse is that Pit actually had a
better recovery in Brawl, where he could fly through the air completely freely, but had the ability taken off in Smash 4. He nerfed Pit's recovery after he actually worked with the character himself.
He's not Sakurai's character. That's why Sakurai made his own Pit.
THIS is the original Pit.
And THIS is Sakurai's fanfiction OC based on Pit.
Besides... Dude, it's just recovery. Recovery is a single part of Smash's gameplay, if you have a good recovery you're not automatically a good character. Let me remind you that Kirby is pretty much universally considered one of the worst characters in Melee.
EDIT: Wow, I thought I was gonna write a quick short post, lol. Sorry if I ended up sounding a bit angry about this or anything.
