The pit's basic mid range tools of Dash Attack and Dash Grab (with follow ups) are pretty fantastic. No doubt they're going to be relying heavily on them no matter what. The speed and range of their dash attacks is pretty monstrous, honestly one of the better ones in the game yet we don't really hear about it. Unlike MK, they actually have other options to compete with though, but are not as rewarded through those two moves as well as MK is. To top it off, he practically has Brawl MK's down smash, heck I'm pretty sure it's safer on shield than Brawl MK's was, it's a little disgusting how much they can get away with "spamming" it (and I don't think it's good that it's relied on as a crutch by many when it really shouldn't be / more rewarding options probably exist).
When I play For Glory and I come across Japanese players, the way they play against Pit is so weird, they overly respect him for some reason that doesn't happen when playing him normally/otherwise, I'm yet to fully grasp what it is, but somehow Pits over there are having that impact on the player base.
Aiming bows upwards though is really underutilized, although I think it's pretty good. Cancelling your run with it and aiming upwards during traps/etc.
Pit's don't use up throw whilst it's giving up air traps for longer than down throw and sets up perfectly well for upwards arrows.
I personally don't use down throw much at all, blame Marth habits, but Forward Throw and trapping people towards the ledge/horizontally proper I find more consistent than 45 degree mid-air trapping which due to his poor aerial mobility, short hop fast fall specs and only one relevant "strong hit" aerial (bair) is kinda lacklustre.
All in all, I just wish Pit's jab was slightly better. He's pretty great at representing a player's fundamentals but falls short in areas enough to inhibit him from being a shoe in for high tier (or greater). His spread of tools make him top 10 in mid-range game play IMO and that incurs quite a bit of dominance/strength on Wifi, which I guess is the primary place you'll ever see the Pits, hopefully we can kinda figure out the missing link between Japan's perceptions of him. Pre-apex I was talking (albeit it not really beyond monosyllabic discourse) to Japanese players and the lack of Pit's popularity in the West was surprising, it's been the itch in the back of my mind ever since; "what am I missing here?".
