Character diversity is all what a game should be about, ppl also talk about how Jack and Hwoarang are mostly in Top 8s from US tekken, ppl tend to forget that Tekken character diversity is based around country preference, you will not see a Jin or Kazuya in Top 8 on a US tournament because US themselves hardly play any mishimas, they play more, Law, Jack, Dragunov, Hwoarang, Feng, King, Claudio, Xiao and so on, the easiest characters to play.
Japan and Korea are more likely to have Mishimas in Top 8 because they play mishimas the most compared to the entire globe.
Kuma is a character extremely popular in UK
Injustice in the last two majors had a good shown of character diversity, despite the amount of Deadshots at CB and the Trait Adams at CEO, game is looking gud IMO.
