you don't always need B too be charged full. mixing it up helps out your game as well. since just shooting B from a certain distance, uncharged, allows you to follow up on someone from the stun. homing missles are better to shot cause they take less time and you can make a wall of them using missle cancel, while just shooting super missles you can't do as well.
being a projectile character means you have to use your projectiles, but mixing up close and long range combat is important too. learn to vary based on the situation. jab from close rande and Dtilt and Ftilt from semi close range. even use the bombs at cose range to space around a bit.
also learn how to use Zair effectively. it will be your main way to antiair air fighters, as well as approach, retreat, annoy, gimp, and combo lol.
