RDM's Embolden gives DPS to other players, therefore it's support and RDM must do lower DPS than other jobs because of it for balance. There is nothing you can say/think/believe/do to change this fact.

Job difficulty should never matter in terms of DPS and game balance. All that should matter in DPS and game balance is how much support and DPS buffing the job adds to others. If MCH offers no DPS buffing and minimal support but still does less damage than a another who offers amazing DPS buffing, why would you ever pick MCH over another? I do want more difficulty and complexity in some jobs' rotations, but that should never, ever, ever be a factor in game balance and how much damage a job can do. The moment it does is the moment jobs become ostracized and unplayable because why play the EZ mode SAM selfish DPS when you can play RDM who offers both Embolden and higher DPS despite being more difficult to play? That's not game balance. That's wrong.

You do tax things on a "what if" basis, by the way. 100%, for sure, with certainty you do. The amount of wipes you can save with Verraise in standard pug PF groups is most definitely worth lowering RDM's DPS for, and is RDM's defining feature.
