Capcom is known for pushing some unusual rules before the Capcom Pro Tour season begins. Right now, the CPT is considering a change in the rules of the tournament season for Street Fighter 6 that some users might find controversial. This change will essentially crack down on fighting game controllers and input devices that don't have a lever or are more colloquially known as "the Stick." This is done to maintain fairness for all players.

The new Capcom Pro Tour ruleset change has maintained studies and reviewed the advances that the fighting game community has made thanks to the adoption of leverless controllers. While not outright banning the controllers, Capcom has made a few adjustments to the controller usage rules to ensure the highest level of fairness. This new rule allows all leverless controllers to operate at a universal standard for Street Fighter 6's tournament season.
This new rule change will force players to either reject or maintain dual direction inputs (so, for example, if you hold up and down or left and right at the same time, you won't be able to perform a motion input in the opposite direction).
