I can't confirm or deny any of that, but I can absolutely attest that SMN does tons of damage with Bahamut in FL. I regularly see 7+ SMN players on each 24-man team, and generally one of them will have the highest kill count and/or damage count. SMN mops up in PVP, especially in tight areas where it's hard to escape... because no matter what, there will be stragglers and they will be the first to be culled.
