Dragon Kick, man, Dragon Kick. The Final Coil of Bahamut should be renamed to Final Coil of Dragon Kick. That ability has such batshit insane utility there, especially in T13. Like nearly all of Bahamut's attacks are magical (auto-attacks, Earthshakers and Flatten's initial hits aside). My group doesn't have a MNK (single melee with DRG) and we do fine, but it feels a lot more brutal than compared with having a MNK. Basically need to spam heals more in situations where you could omit a heal having a MNK present and then some people might need to gauge more VIT via having one more accessory on them, which cripples more of their main stat from that.
