Something I've been considering using in my own campaigns instead of the standard Hand-to-Hand Attack Power and martial arts maneuvers is a limited form of Strength.
In several official Hero System write-ups, I've seen limited Strength used with the Limitation (Only to simulate Exert-based martial arts maneuvers; -1/2). The same character would also take Hand-to-Hand Attack to represent their skill with striking blows.
My thought was to buy STR this way instead: +5 STR, 0 END (+1/2), Hand-to-Hand Attack (-1/2), No Figured Characteristics (-1/2). Real Cost: 4 points.
Instead of plunking down points on martial arts maneuvers, the character could buy this form of limited STR and 3-point Combat Skill Levels that could work with this power and Block as well. Points-wise, it would be about the same as buying a string of martial arts maneuvers, but you would lose the negative combat modifiers of normal martial arts maneuvers. I'm not sure how you could incorporate that.
Thoughts?
