Dragons Breath Not KBing Properly

Issue/Problem/Bug: Dragons Breath does not Knock back properly.

Describe the problem. Be as specific as possible!: When using Dragons Breath on certain monsters, such as Papulatus, the monster does not get knocked back. This is totally unfair, seeing as Rush, Corkscrew, and Backspin Blow can knock back ANY monster 100%, unless it is stationary. There needs to be a little more balance by making Dragons Breath able to KB all monsters, or make the other skills unable to KB all monsters.

I believe the same issue happens with the NL's kb skill.
