My suggestion for how to fix the current "Synergy Stacking" meta.

It's certainly true that they do actively tune PvE output, it is a big part of the game after all, and the impression of fairness is important if you want to maintain good relations with your playerbase. However, where perception comes into play is the fact that when it comes to DPS differentials, the tolerances that players expect are invariably an order of magnitude tighter than the target SE themselves aims for.

The competitive nature of speedrunning and the players that take part in it mean that any difference no matter how small gets magnified by hyperbole and the all-or-nothing nature of relative performance. As long as something is measurably better, it will be seized upon as the new hotness and people will find another set of jobs to complain about. You just can't win with these people.

There's also the matter I brought up of there being many disparate and valid avenues of battle content in the game. Selfish jobs like BLM and SAM already do disproportionately well in small group content where there's less opportunity to exploit the compounding effect of party buffs (not to mention less people to buff). You can say such content isn't as important as savage or ultimate, but if that was the case, why would they repeatedly nerf things like SMN's painflare when savage has no meaningful aoe? Things like that make me suspect they take a more holistic view of job balance.

So if you ask me, how this pertains to balance w.r.t the raid composition metagame is that optimal compositions should be treated as emergent phenomena, not the baseline for comparison. Different toolkits flourish in different niches in this game, jobs that excel at aoe and personal contribution excel in dungeons, RDM is a solo wizard when it comes to things like PotD - so I don't see why it is so offensive to people that jobs with synergistic buffs excel in an environment that lets you compound them. The fundamental challenge of raids is simply to clear them, and any auxiliary conditions you attach to that outcome are self-made. Remember that the etymology of the word 'metagame' is literally the game within the game. When you operate on the fringes of the playerbase and are making up your own rules, you have to be prepared to accept some concessions, it comes with the territory.
