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

Lots of talk about "Rational Gaze"

If you check this guys posts on Reddit, you'll see that he pretty much says people are being over-dramatic about the SMN issues and that the gap between BLM and SMN when equally skilled is not that huge. He also says his dps are "more or less in line with the blms in my fc".

He does however think SMN should have a slightly higher potential dps than BLM.
