There's one thing I want to point out:
It seems all the American Pits are knocking on Masashi's use of arrow spamming. This makes it appear to me that, in general, American Pits don't make much use of arrow spamming outside of using it for edgeguarding.
This is evident in videos I've seen that feature Kupo, Sagemoon, Skip, Kown, and Aisengobay.
Masashi, however, makes far more prolific use of arrows. However, he's not as generally skilled as the American players listed above are.
This means American players are generally better players who turn their back on the arrow spam.
Frankly, I think all you American players who shrug off the arrow spam are severely crippling your game. There is no reason why you shouldn't completely exploit your huge ranged advantage while at the time using all the skills and techniques, I've seen you all display, for when they manage to successfully approach you. Outside from "honor," that is. But honor doesn't win tournaments.
There is no need for Pit to approach anyone ever. Everyone knows that approaching is dangerous as hell is Brawl, and whoever has to approach always starts at an initial disadvantage.
Arrows are the best projectile in the game, all factors considered, and I don't think anyone can really dispute that. And the shield is the best reflector in the game, allowing redirection of opponents, protection from non-projectiles, as well as prolonged holding duration.
Even against reflective characters, you win. Start a spam and you start mindgames with your ability to change your arrow's direction mid-charge as well as mid-air. Any reflective character who plays defensively will be ready for an arrow, it doesn't become hard to take easy advantage of their ending lag on their reflective/absorbing moves with an easy approach that way.
So what I want to know is:
Why don't I see any of you competitive Pit mains use the arrow spamming to a much larger degree, using it in synergy with your combat skills?
To me, it's the most effective playstyle. Making full use of your techs and combat skills when your opponent has approached, and using the arrows to make them approach.
Pit doesn't need to approach! He's the best camper in the game because he's so good at being on the offensive as soon as you enter his camp. Why not make the best of both worlds?
Fights against Marth especially... why wouldn't you spam him first before eventually facing the range and power of his sword?
