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

They are fine lol. I disunderstand the gracious amount of issues with SMNs. It stemed from FCoB Mana issues and choosing BLMs over them, but some fights favor other classes. Most of the complaints I feel aren't from people in final coil lol. Many groups are successful with SMNs in their groups in final coil.

That's right. my dpses in FCOB are (with 120WP) : T10 430, T11 400 (Cube with Ifrit, cause our static has blm and smn), T12 430 (handling bluefire)
i think those dpses are enough to clear for FCOB though i didnt cleard t13 yet.
but, melee is specialized in one target and caster stronger than melee in AOE in almost MMOs.
compare to another caster;BLM, my static's BLM show that more dps than mine 15~20+ though we have similar gears.
besides, my MP was drained out in 5min without energy drain, cause FCOB have many adds except for t11.
so now there aren't certain reason to play SMN, exclude only playing SMN player like me.
