Many have spoke about things TK8 could balance in season 2, but it's worth stressing about the ranked system as well.

SF6 Master rank was controversial at first, but turned out to be a great decision.
You can achieve it with a win rate lower than 50% (if you play a lot), and you never lose the rank.

But then they added a true elo system, so if you climbed it "cheesing", then you will drop some points and eventually find people your skill level.
The MR system is also an incentive for veteran players.

TK8's GoD rank right now is just a curse. You find less people 'cause the ones that achieve see no reason to keep playing or the players that are not strong enough to keep it just stop playing.

Plus the matchmaking is bugged, so there are times you find nobody or just one player over and over again.
I hope they have plans to change these things in S2.
