I think were in the same camp just looking at different where things should be. If I were approaching balance I would like to see 'tiers' of damage and adjust based off the amount of rDPS a jobs brings to their personal output. The lower tier a job brings personal damage, the higher it's rDPS support should be, and then within those tiers I would apply the hypothetical "mobility" and '"rez" taxes. The only job that would be tough to classify is NIN, as we don't know how reworked NIN is going to approach Trick Attack. As it currently stands it's still the most powerful raid DPS utility in the game, but it might not stay that way, but I will act like it remains that way.
