That's true if you look at single player games, but should rarely be true in multiplayer games where people compete with one another for results. It's an extremely difficult line to tread. Imagine Summoners were able to do 5k DPS if you were a literal god and did everything correctly; How would the people who are amazing at BLM feel about being that good? No matter how good they are, they can't beat the best Summoners even if they can beat most.
No. I think a world wherein the top players of both jobs bring equal benefit to their party. The reason to pick a class with Summoner's current kit is because you enjoy the challenge; needing to be better to match someone is just part of that. Classes should be balanced with the absolute highest possible output in mind; if the average summoner is worse than the average black mage, but the best summoner is equal to the best black mage, I think that that's fine--It's just a difference in the complexity of the jobs.
You keep saying Summoner being complex is bad; "kicking the class while it's down". You shouldn't need to compare yourself to other players to know whether you enjoy a job or not. When you enter a raid and pilot the job, do you enjoy yourself? Ignore numbers and tuning. Is it fun? That is the most important question. Balance can be achieved by changing some numbers, but to imply the complexity of the job is negative is something I take issue with; The complexity is why I play SMN in the first place.
