Ight I'm back home. Had some drinks so beer with me (see what I did? I made a funny -.- )
Basically I agree with a some of the grouping, with a few exceptions. But nobodies listings are 100% identical to mine so that makes sense. Only things I would "strongly" disagree with is that Liu is too high literally sitting between Shinnok and Lao, Kitana is too low, and a few more characters need to be with Jacqui and Takeda.
What I think has to change is your lettering. You have everyone in A tier and up outside of Goro, Takeda, and Jacqui. This isn't Tekken level balance lol. You know how good a character has to be to be considered A tier? There's no way possible characters like Reptile, Kotal, and Kenshi are A Tier. Just like there aren't 8 S Tier characters. An S Tier character is Kabal and Cyrax of MK9, or MMH of Inj. For example, in Injustice it is likely that MMH was the only S tier character, with Batgirl, Flash, Zod, and Aquaman being A+ Tier. Maybe one or two can also be considered S, but not all of them. By your lettering, you're basically saying 25 characters in this game, all except for 3, are either as good or better than Superman, Sinestro, and Bane were in Injustice. This would mean that characters like Kotal, Kenshi, Johnny, and Ferra/Torr can win fully stacked majors solo without having uphill battles when playing Lao's QC's, Predator's and Raiden's.
Depending on how big you think the gaps are between brackets of characters, it should be some sorting of that looks like-
S Lao, some other person or two
A+ Cassie, a few characters.
A Jax and a couple.
A- Kung Jin and a few.
B+ Ermac etc
B- Johnny etc
C Takeda and a few
D Solo Goro
It should be categorized more like that for a better idea of where characters are balanced. Unless you believe 25 characters are Superman level and up then that would be a completely different convo altogether lol.
