I have this vision one day a Pit player will emerge that can somehow fight normally and maintain 4 looping arrows at the same time, because he had his corpus callosum cut or something, and will start winning all the tournaments.
Like that'll ever happen, for trying to maintain the loops while fighting is risky considering that should you get hit at the wrong time, you might DI towards the direction that you were sent flying at, which might cost you a stock.
I even tried maintaining some arrows while trying to fight, and I find it a very difficult thing to perform.
Pit is considered to be a very versatile character, which he is. He has a little bit of everything, except obvious things. The few things that Pit is pretty good at is holding his own when camping, and good airgame.
As we have mentioned this many times, the BIG Flaw of the Up-B, and then his lack of KO power is what Pit has problems with.
I would have to say that Pit is somewhat technical, and does have a lot of options against basically any char, though some are harder than others. In my opinion, Pit would have a slightly harder time with the smaller chars mostly because it is hard to hit them, and you'll have a harder chance to perform small combos.
Back to his tech, there are easy ones and then hard ones, but that doesnt mean that you shouldnt practice them. Simply practice and not only will you get better at them, you'll also have extra options in battle.
I've mained him for 5 months, and I remember the time where I was learning about arrow looping, and arrow rain, which I am very attached to. Eventually I learned the other stuff like Wingdashing (many ppl still think it's useless...), Glideshifting, etc. Certain AT have bigger uses than others, like ppl hating Arrow Rain, but I use it for my benefits. AT arent required to use Pit at all, but they are simply to give you much more options in fighting. Use them well and you could perform things that you couldn't do without the ATs. There could be a lot of Mindgames when you use some the AT, like Wingdashing, good for mindgames, just like arrow looping itself.
You just gotta apply the tech correctly, practice, and you'll do good with it. That's how I got good with Arrow Rain, which was basically considered useless. As said before, I found a way to make it beneficial to me, and practice was the start of it.
Note: I was lazy when typing this, so should something be wrong, correct me.
