I think the complaining about a lack of female characters is silly. Why?
Because literally half of the cast has not been revealed. So we don't know. Just because it's not in a reveal trailer does not mean its not in the game.
yeah ...
MK 9 : 32 characters, which 7 of them are females
Injustice : 30 characters , which 8 of them are female
So, if MKX , starting with 24 characters in initial roster, just presents at least 5 females characters, that's good enough
With DLC, if the numbers rise to 7-8 female chars in the final , nobody will not have any reason to complain about it
