And yet, this is all amount to tilting at windmills because:
1.) It is good that some jobs can pop off, that means there is atleast some nugget of nuance in the game and its gameplay
2.) And you will never eliminate the natural variance that changes each balance patch and then once again each raid tier.

If the playerbase reinforces their god given right to get even less tolerant over "balance measured as damage differentials", which have been WORSE in the past too, then the development team can only either:
1.) Force you to play with people you don't want to.
2.) Make DPS checks so unbelievably easy that you do not care anymore about those damage variables.
Pick your poison.
