I made all characters which are more range like john, henry etc more spamish.
Those projectiles can all be dodged with counter or evade skill depending which char you play.

This removes an important game play aspect of these characters: aiming. If your D>A spreads out 20 blasts the players influence by holding up or down to aim becomes minimal. That's incredibly boring. You removed the dimension of aiming and dodging (by actually moving around) and replaced it with single input actions. Instead of the 3 options (up/neutral/down) you now only have one.

Stuff like LouisEX palm or Firzen arctic volcano are stronger but is slower so they can be dodged easy.
Those attacks are rather OP but almost impossible to hit. That was intended.
So its more satisfing feel when you actually have enough time to charge up and hit with arctic volcano lol.

However this makes them fully useless against real opponents. And once you know the distance you gotta have for a computer opponent to walk right into it that becomes a boring fail-safe tactic too.

When I play this 1 v 1 against computer all characters are balanced and can beat each other.

This is a lop sided test. How well is this balanced for computer vs computer? (create a character that deletes itself to test that)
How well is this balanced for human vs human?

Also you mentioned computers not really using your new features.
You could try to write them some basic AI that exploits them as much as possible to see how balanced things really are.
