you can swap G and B+G on default pad controls so u can block while charging. plus this doesnt affect playing other characters. you have to grab with the A button (B+G) while charging A attacks, but it's managable like using A or B attacks while charging A or B. Though I dont know if theres a way to make K attacks easier while charging without affecting other characters. you have to claw ur index finger to kick while charging. Any solutions that dont handicap another control?
