In the game's files that are more Kombat Kard customizations including borders and something new named badges. Given how they look, they are themed/colored, it's easy to assume it has to do with a ranking system. But if you look at the file names it basically confirms it. Taken from the file names, it looks like the rankings are:
The current "ranked" mode feels like a placeholder, honestly. There doesn't even seem to be any matchmaking algorithm. I sometimes watch Titaniumtigerzz' stream and it will match him up with people that have 0-3 total games played on the regular.
Don’t think it’s this at all. Game was obviously rushed(no word from nrs about numerous subjects, dlc chars hush hush probably still in development, kombat league date pushed back numerous times and custom variation system last minute turning into 2 variation system), and probably will be playing catch up for a half a year.
