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

The idea that sufficing as a class policy is not true at all because BLM got buffed, MNK got buffed, WAR got buffed and all these classes were good enough to clear coil. The original BLM buff was because it did low damage (in comparison to melee). But there was proof out there that BLM could do amazing numbers (Lipton IceTea and his BLM friend). They were even top DPS in there solid group. So BLM has good numbers.
Also, the main complaint? According to who? It's an issue, but a lot of people have uttered their complaints on the DPS issue. It's very simple. Comparative analysis between classes, especially caster classes is a good thing. If our parsers make out an obvious gap between BLM and SMN and if SE comes to other conclusions, then they have an obligitation to share those conclusions in order to justify not giving SMN a damage buff. All else is useless speculation. I seriously dislike how you reduce it to one complaint, it has been handled and now everything else seems to disappear in the background? The argument that casters are competetive (raiding spot) and the idea that BLM has infinite recourses and better damage is enough reason to buff them. That is the argument, it hasn't been refuted and it never will be. But if it's true, that parsers reflect a distorted reality regarding SMN DPS, then prove it and prove in what way it does. If not, again, pure and useless speculation.
