if it's a combination of long range and CC, wouldn't you just add the CP points together?
but just as an asthetic question, how is a chainsaw sword possibly even PART long range? the only thing i can think of that makes sense for this combination is a gunblade.
@Foggy: Your formula is right, or at least, that's how I'd do it. ...But if he had meant the chainsaw thing from GoW (I don't care what it's called, it slices aliens in half!), he'd probably have said it.
