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

Then your BLM is alright, but not super great. A good BLM will easily get 500 DPS on both T10 and 11. On T12 a good BLM will get 480+. And on T13 on my BLM I push 460 DPS (unmerged with a lvl 120 weapon).
Most of the complains that come from people who clear content are legitimate and are blindly disregarded by Skeith, so it would seem. There literally have been 30+ treats by now discussing the summoner issues.
One of the biggest issue is the MP drainage and being punishing for being a good Summoner. The second issue is that the damage is not sustained at all, especially as the fight drags on. Summoner DPS drops and drops and there is no real way to get it back up, even with Fester. Third issue is that the gear is not optimized for Summoner.
Skeith is full of shit because I know at least three servers where Summoner usage has been falling like snow in Christmas.

Summoner should still have HIGHER ST DPS than BLM.

i agreed all your 3 issues. but i cant believe that blm easily get 500 dps lol. http://www.twitch.tv/saerysthia/c/5653653 a month ago video.

In that fight scholar is using selene all of the time and that give BLM pretty big boost over SMN. In harder fights like t13, scholars is gonna use more eos and that make lower gap between BLM and SMN. All SMN videos that I have seen from t13, BLM and SMN is doing pretty much same damage in the end of the battle.

Woah there guy - calm your ass. Your comment is so full of bullshit that I am literally blinded by your ignorance. There is nothing, nothing at all, stopping SMNs from doing great in final coil. I don't care about your largely made up bullshit numbers, kid. SMNs are fine. Can they use some tweaks? Yes - I'm not arguing that. I'm just saying most SMNs feel like they are in DRGs position.

Don't come spouting disrespectful retorts, kid.

Says not to come spouting disrespectful retorts
- Replies in a demeaning unrespecful way.

Seriously, you are just that kind of dude, aren't you. Instead of refuting what people say, you resort to being a hypocrite (by doing the same thing you excuse others off and just calling the arguments or remarks bullshit). No one ever got any better from that kind of dribble. Because obviously you don't get the point, at all. It is true that Summoner can do quite well in Final Coil. It is however also true that it is outclassed by every job in the DPS department but Bard.
And in all fairness, Summoners are a bit in a DRG position because Dragoon could also do alright in Final Coil. It just wasn't viable in comparison to Ninja or Monk. The same goes for Summoner to Black Mage. Is that so hard to understand?

You expected me to be calm after saying that I'm full of shit out of nowhere?
I said I "feel", openly showing that I'm speaking from what I've seen. It isn't my fault you skimmed over and found offense in my comment. Your anecdotal claims – your "I know" comments – aren't viable in arguments. Also, you aren't the word on what a great BLM is either, as numbers could largely depend on the strategy used and RNG.

DRGs were being denied in the FCoB because they weren't able to survive unavoidable damage. Even Yoshi-P said that himself during the London Fan Fest. SMNs are NOT in that position. I already said they should get some tweaks. DPS buff and some sort of Mana tweak. I don't believe it should be nearly as grandiose as I've read from posts here, FC pages and Reddit. SMNs need tweaks that would fit their class. Remove Contagion off of Garuda, and let it affect all DoTs; 2.5x pet DPS and slightly reduce DoT damage; pet combos. Something other than forever sustain+huge damage.
