I'll be honest, when I first heard that custom variations didnt look like they were making its way to competitive I was kind of bummed out. After reading some of the responses here I kind of have a change of heart. I mean, with so many different combinations of moves, how many matches would he lost strictly due to character unfamiliarity and not actual skill? If you lost to a character in mk x or injustice 2 due to lack of match up knowledge, it was essentially your fault. If custom variations are a thing, it will be virtually impossible to "do your homework". And I dont think a single best of 5 is enough time to get used to fighting a character. I mean think about it, every match is essentially going to be two people probably playing against something they never played against before. This is quite the opposite of competitive in my opinion. Part of the beauty of fixed variations/characters is that you can lab and know each character and how to deal with them, so it's essentially up to you to know match up knowledge
