FFlogs and xiva are important tools to improve and a core part of raiding in every game.
They help you analyze your own gameplay to make good, informed decisiones. Everything else is feelycraft and freestyling and results in more responsibility for others. Critical players with a good self-awareness will notice their mistakes the moment they make them but even they cannot reconstruct a full 10min+ fight, let alone objectively.
Things like missing uses of important cooldowns, lack of uptime/ dot uptime and clipping will be shown there and have far more value for you as player than just feeling good about a run or being content that the boss got killed. If you want to keep doing endgame content I suggest you make use of those tools aswell.

They also help illustrate flaws in class design and balance for the devs because no dev team will ever be able to test classes as extensively as millions of players can. Nor will they be able to foresee every way players might utilize skills to cheese mechanics. Many quick fixes and adjustments were made between patches because players are bound to find loopholes in design and will happily exploit them.
Most MMOs have beta servers for this purpose so the devs can get a rough idea about how things will play out in practice but then they often have to hotfix things because players still found more loopholes and flaws to "exploit".

In a game with a clear dps meta, dps balance is important for every single role or classes will inevitably get benched. Sb heavily favoured Sch/ Ast comps to the point that even pugs tended to exclude WhM on many data centres because by taking one along they were already at a noticable disadvantage.
Healers and tanks are not immune to the effects imbalance brings just because they have a green or blue icon. Naturally, people are worried if they notice certain classes or comps are starting to fall behind. Escpecially once power creep starts to kick in which favours any classes with % based buffs over flat damage.
