How are you losing? Injustice was made for scrubs and there is no fundamentals in the game. All you have to do is pick up a top tier braindead character like Super-Man or Black Adam and you'll be good to go. Make sure you do lots of jump in attacks and don't worry about footsies cause they don't really exist in IGAU.
No, practice makes permanent. Only perfect practice makes perfect.
Dark Souls, the most frustrating and infuriating game known to man next to Castlevania and Mega Man, which I still say those are easier than Dark Souls.
Not really, of that were true random ass players would be placing, but that isn't the case.
But if practice makes perfect and no one is perfect then why practice?
Ok, so from what I am gathering, here is your main issue:
Start collecting 'tape'. Stick with batman for now, start watching footage of good tournament players, and see what they do. Steal it. Read about it if you don't understand it. Ask for help.
There are only like, four characters in the game with an air dash. You don't need to block low during zoning unless you're fighting against Adam, Nightwing or Deathstroke. Stuff like Aquaman's From the Deep, Frost's icicles and Manhunters pillars are all mid. Most projectiles in the game are high, overhead or mid, so you can block most of them standing. Low projectiles are rare.
True blockstrings are overrated. Bruce has many safe block strings.
Gadget characters are more than able to abuse interactables. There are several maps that benefit gadget characters more than power characters. Part of being a gadget character involves destroying things that power characters can use (atlantis globes for example).
Batman has so many high/low/overhead options it's a bit silly.
Not sure what this means. If the animation has "finished", but your input isn't coming out, then you're still in block stun. Hit the lab and work out when you actually need to do your input (For reversals, I assume?).
That's because Superman is braindead and requires very few moves to become somewhat decent.
Please don't. Pick someone who you're comfortable with. You won't advance as much as possible if you simply pick someone who's powerful and don't make any sort of connection with. I mean, sure, if you really do click with Supes or Adam more than Bats, go ahead, but don't pick them up simply expecting to faceroll people consistently.
The only thing I would add is that Batman has strong anti-zoning, if you use his grapple properly. Use it to pull your opponent in close where you can do some hand-to-hand. Batarangs also punish zoners. And remember, you can use the trait bats to block for you! I have found his double jump to be no good because he hangs there so long that your opponent just AA's you. However, you also need to remember that you are playing a human being, not their character. Jump over them, maybe a few times to confuse them, then him 'em with a throw or the mid-screen interactable. That jumping back and forth is a form of footsie, if you use it right.
. When it comes to blocking practice really does make perfect. If something is confusing you ask your friend about the string. IE: Frame data, Low, Overhead, Etc. The way i got better at blocking was learning to block Batman in the Demo of the game. Good times. Good Times.
Maybe you should start asking yourself how much do you really like this game. Because if you really like a game you will not lose your motivation to improve ESPECIALLY if you keep losing. Things like "Maybe I'm just not cut out for this genre" are bullshit if you ask me. Sure, some learn faster than others, but that's not so important. The important thing is the will to learn. If you really like a game, you gonna have will to improve
