well, as a combo starter, i grab to down throw, then jump and hit with the flame sword, wait till they hit the ground, and i let them get up, and immediately "fake short fast hop" at them, wait for their response. if they hit mash a, i powershield, then proceed to shoruyekn. depends if i get sour spot or sweet spot to calculate my next move.
i find that megaman is more about a i hit, then watch to see wat you respond with, and respond with an appropiate move afterwards.
sometimes i even stand still.
literally, i don't move anywhere.
and my opponent charges in
and throws a dash attack that can easily be punished
with short hop to flame sword, or power shield to sweet spot lemon, or short hop fast drop to shoruyken.
trust me when i say this, you'll confuse your opponent a whole lot if you just do nothing to them. or walk up to them like you're going to attack, but you're just baiting them, and you proceed to punish
