Using the current control scheme, the only other option to change sets is to hold R1 and press the D-Pad or one of the four main buttons to change to a specific set. Having to press R1 repeatedly in the middle of battle to change sets can be bothersome, so we've thought of the following solutions.
・Allow R1 to only toggle between specified hotbar sets.
・Allow R1 to only toggle between specified hotbar sets when your weapon is drawn.
The above solution would allow players to separate sets frequently used in battle from those used in a more leisurely fashion, alleviating the stress of switching between hotbar sets.
