The way I see it, in the balance department, NRS would have a lot more options to balance the game in a better way if Kustom Variations are allowed.
If a Character is too strong they could look at his base kit, and decide if everything he has is ok or if he has a little too much and a move or two could become abillities instead of base. If what makes him too strong are the moves he can equip but they are not too strong by themselves, just when used in a certain combination, just change them so they take more slots. If a single move is too strong, just balance it. If a certain character is not that good they could do the same thing, they could even add moves like they did for some characters in injustice 2 if they are considered in lack of something.
It also adds longevity to the game. Imagine having a season 2 with new Krushing Blows, Fatalities, Brutalities, Kustomizable Moves for every character... It would give them the power to keep things fresh and interesting for a very long time if they want to.
I really think this approach would avoid the overnerf/overbuff situation and be better for the game in the long run.
