Can someone give me an in-depth explanation why Summoner is arguably the worst DPS?

That's by design. From the start SE wanted to make certain jobs more difficult to get maximum performance similar to MNK vs DRG. You say that BLM is better than SMN in all aspects but maybe the SMN you're judging against was subpar therefore had a weaker output. Also SE has confirmed SMN has a MP issues in FCoB, not that they are weaker than other classes.

I don't think you realize how weak this argument is. There is a standard of SMNs that have to go quite above and beyond normal gameplay, including myself to achieve these high numbers and quite frankly it is most definitely imbalanced vs. BLM. The effort I have to go through to achieve the decent numbers I pull, is very high where the BLM I party with while he plays very good as well, is surpassing me with relative ease in EVERY environment.

Why were DRGS buffed exactly? Simple, to compete with Monks and Ninjas that were taking over the meta in the raiding environment. Not to mention the issue that forced SE's hand (imo), of all the magic based mechanics destroying DRGs.

SMN needs an adjustment to ease it or reward it. It is quite possibly the hardest class to play and maximize on versus any other class. To then go through all that work and still be lower then every other DPS outside of a BRD (playing songs mind you) is really really bad, because you basically kill the class by it being unused. Some of the best SMNs even on these forums, generally agree something needs to be adjusted to ease the DPS discrepancy. They tend to also post more subtle QoL changes which can affect the playstyle to make it more MP sustainable. Do not feel crappy SMNs are suggesting for buffs because it is generally anything but that. THe raiding enviorment mainly FCOB is hurting SMNs. If you have to jump through hoops and ladders to keep up with the rest of the classes that dont have to do that only to fall short of other classes anyway. That is a problem that needs addressing.

Either the class needs to be rewarded for putting in all that extra effort, or it needs to be MP solvent to properly utilize all it's tools to DPS. We should be able to DPS on this class, not have to sacrifice our DPS, which is already in rapid decline throughout a fight, just to keep going. It' makes no sense to contribute to the negative trend that is SMN DPS by utilizing a tool that is supposed to "help us" when it does anything but.

Mind you I'd llike to stress the point that recently they acknowledged an MP imbalance to actions vs other classes issue, which means yes it IS an actual problem.
