Some views on DPS balance that everyone cares about

[Lastelli]

Even IF you were to assume that was True, it STILL would not mean that ALL BLM, DRGs, SAMs put out extreme effort while magically and mystically its ONLY Summoners who don't give a damn.

ALL jobs would have some who would do that and some who would not, so the Numbers would not magically and mystically put Summoners at the bottom of the pile like that as if they were the ONLY ones blowing it off.

The reason why SMN is relatively weaker in dungeons is because despite having a very good aoe burst dps its sustained aoe dps is lacking compared to most other dps jobs. And nobody cares, because in remotely challenging content (ex trials and above), sustained aoe dps is useless. As for alliance raids, they're such a clusterfuck that they really mean nothing and fact that the data is so different from data found in ex trials and savage raids that have a more or less controlled environment should be more than enough to ignore them. But just for the sake of argument, sustained dps jobs appear stronger than they are there because of things like multiple trick attacks and staggered party buffs, combined with the fact that alliance raids display dps instead of rdps.

It's also important to note Actions Per Minute for DRG is 39.4 Average, and so is SMN, SAM is at 43.8 , BRD 45.1 , MNK 39.4, Ninja is at the upper end 47.7 , and BLM is at 31.5, If this game was actually balanced jobs that have to do the most actions per minute should be doing the most dps, of course with the exception that some jobs have more risk to reward then others.

DPS should not be balanced around apm, and thinking about the hypothetical where there's a dps with a one-button rotation and a 1 second gcd (=60 apm) should easily make you understand why.
On the other side of the spectrum, BLM is currently the lowest apm job (including tanks and healers) in the game, despite being relatively more challenging to optimize. MCH is the second highest apm job in the game, despite showing the lower damage variance between median and higher percentiles, meaning that it's relatively harder to score a high ranking with it, because it's a very straightforward and forgiving job so there's not a lot of optimization to do. So no, apm means absolutely nothing in this game and is not a good metric of complexity, therefore it should not be considered in the balancing process, especially because in practice you won't even feel those 5-6 more actions during a whole minute. Many people go as far as to say that difficulty in general should not be used as a variable to balance dps, let alone apm.
I'll also answer to another post of yours: smn hps is all overhealing, either for the smn or for the healers, because whether there's a smn or not, healers won't change how they heal. Another reason why smn regen is useless is because weak regens don't go well with how aoe damage happens in this game, which is why they changed medica 2 and aspected helios in ShB.
