I don't think anyone has ever stated that battle res is not important nor an advantage that helps complete content. It's just stated that battle res coming out of a SMN in final coil is highly impractical and essentially reduces the class' capability to a point in which they become DPS inefficient in a min/max environment. The SMN/BLM BiS and stat values are of significant different for each respective class. BLM wearing the same gear as SMN would or vice versa would result in quite a significant DPS output difference.
There are plenty of utility skill that the SMN class has but none of them are required due to the fact these utility advantages are not class exclusive. Therefore such are not truly advantages for taking a SMN over another class. Every raid runs a SCH for Super-Virus, Eye for an Eye can be cross classed by BLM/WHM/SCH, and WHM/SCH both have battle-res.

Why would any group take the DPS inferior SMN over any other class when the utility they bring can be gained elsewhere from more essential classes?
I believe this is the question the majority of world competition teams would ask when considering a SMN in their starting lineup. Where does SMN fit in at this point in endgame?

The currently low output and sustainability of a SMN in a lengthy fight, in which they already suffer from mana problems, wouldn't allow them to use the utility skills they are provided and maintain their place value in a DPS check situation. (Unless over geared and/or high raid DPS.) Like I have stated many times in the past, this does not at all mean the SMN cannot complete the content, only that they are non-optimal due to their value in a min/max situation.
Outside of running double-melee BRD BLM, I know of no composition or team that had managed to complete FCoB in the top 3 kills with a SMN.
I wonder if it is possible for a SMN in only i110 pre-2.4 gear, along with the raid in the same gear, to complete FCoB and meet the DPS check.
Perhaps Lucrezia could switch their BLM with a SMN on their next i110 only kill and prove myself and every other SMN who believes there is an issue with the class entirely wrong.
Though I do believe even if they did manage it, it would come at a cost of a significant increase in difficulty, time in content, and the necessity of some major RNG luck.
The issues brought forth are not about the SMN class ability to complete content, but the imbalance and technical problems the class suffer from on a base level in comparison to all other classes. I would imagine if all other classes had these issues then it would just be a natural part of the game. That, however, is not the case.

Just as a request to those stating that the SMN class is fine:
I have stated and outlined many of the issue present in multiple postings; can you refute any of the issues and explanations I have outlined? If so, please do, as I would love to converse with players with whom I can share knowledge with and theorycraft the class.
Any breakdown of why I am wrong or where my estimations and analysis' are incorrect would be appreciated.
