Currently STBS is played 65% more compared to the most played setup after it and 52-3% more tha every single other setup together (101 copared to 96 everything else combined)
I kinda think this is unfair to every other setup. People play STBS because it fills fast and its relatively stupid and easy to play. Also quick too.
A favourite in the setups just kills the point of the competition if all play the same setup and ignores all others.
