Yes I am. I understand this is a very hot take but I consider it an interesting point of view.
A reward means there is a series of action that leads to said reward. Raidbuff are just that, granting a raidbuff.
The DNC or any rDPS job, is unimpacted if the group is taking advantage of the party buff or not.
If they don't, FFLogs punishes you by giving lower numbers and the game punishes the whole group if they don't meet the requirement for the DPS check.
Ask yourself the opposite question:
Are you rewarded if your teammates makes 100% use of your raidbuff?
No, your gameplay remain the same, your DPS remains the same.
FFLogs will show you bigger numbers, because they reattribute what the others gained from your buff to you and your group will have a higher DPS.
It's important to make the cut between the player and the group as a whole. Which entity gets the reward?
The DNC isn't "rewarded", it's the group as a whole that gets rewarded for making use of the buff, resulting in bigger aDPS.
It doesn't, you're still thinking of it as a "reward for the DNC". rDPS is a team effort, it shows your contribution to the group, not your skill level.
It's not meant to show that you are better because you have a bigger rDPS, but that your group has a better teamwork.
It doesn't matter that the DNC can be superior or inferior, the point is to show that the Dancer partner mechanic can be exploited in such way. The topic isn't that there is a ceiling and a floor, but that the ceiling can be pushed to ridiculous heights.
