To me, the Crash Bomber is worthless. It takes far too long to trigger and opponents can block the whole thing by shielding, jumping, dodging or just run through the whole thing and past you. Even when you do successfully land one, they can avoid it by shielding and Megaman doesn't have any reliable moves to shield break at a distance.

I only use the Crash Bomber when playing keepaway. It rarely works and when it does works the opponent has already ran up to me and I get caught in the explosion. It's only actual use is pressuring the opponent, something which Megaman is a pro at anyway.
