I wonder if part of the problem with a variation system in MK11 is that people can see the moves that they don't have access to, and that leads to a sense of a character being incomplete.
That might be the case for some people, but overall I don't believe that's the case.
In
Mortal Kombat XL, you pick a game mode,
any game mode, select your Variation, and start playing. You're picking the same three Variations no matter what game mode and you know what you're getting.
In
Mortal Kombat 11: Aftermath, you have preset Variations only available in "casual" modes, and then you have "kompetative Variations" available in Tournament, Kombat League, and Ranked. This is not explained well at all, and when the game launched, people had a hard time finding how to practice using actual Tournament Variations in practice mode. Turns out, they're not there at all and you had to actually make them as a custom Variation.
That's bad design, plain and simple. They finally patched in the option to select them in Practice Mode post-release, but why was that even an issue in the first place?
And still to this day, if you want to play any mode that's non-competative, you'll either have to create the kompetative Variations or use "casual" Variations. Even if you use Kompetative ones, other players/the AI will be using Custom stuff.
The Variation system is
not unified in this game, and it leads to an incomplete feeling.
There's also the trailers that show off all these moves that aren't even in kompetative modes that disappointed people.
But...the complaints are valid... so I don't agree people should shush it for the convenience of those who like the game as it is.
There's a difference between constructive criticism and complaining though. Complaining usually accomplishes little and is, well, not constructive. It tends to not point out our discuss issues properly that lead along the lines to resolutions. Constructive criticism, on the other hand, is feedback that can be properly used to make improvements.
Storm is a great, friendly guy, and he gets the above distinction.
