An Agenda for Warrior Improvements

[Professor Frink]

I'm unclear on how this "double-dipping" with rage is supposed to work. My understanding of the system was that in general the extra damage you get from rage is determined by the speical ability, not a multiple of your character-sheet damage.

So total damage
= base damage (character sheet auto-attack damage) + base damage (rage generation) * special ability damage per rage (fixed)
= base damage * some constant bonus for being a warrior as opposed to a priest

Is this incorrect?
