I think we've established that the semantics angle is a moot point unless YoshiP himself shows up, what with definitions being vague and the risk of things being lost in translation. There wouldn't be 11 pages of this if it was crystal clear.

It would however, make for more diverse raid compositions making MNK's blunt resist down a proper counterpart to Disembowel. NIN of course have Trick Attack, so all 3 melees would be nicely set against each other.

That's a tie and a point for blunt, so I proclaim blunt damage the winner
