I will also make a note that Samurai, like Red Mage, has a hybrid single target and AoE rotation at certain numbers of mobs to be most efficient. At 5+ mobs they should be doing the pure AoE rotation without any of the single target buffs. At 3-4 mobs, however, they should be buffing themself with the single target Jinpu combo as needed interspersed with the AoE skills. I think also including the Shifu buff for AoE on small packs works out to a loss...? I'm not completely up on SAM dps to know for sure. Perhaps to someone not aware of how Samurai plays at all and who doesn't use a parser, this might appear to be just single targetting since there are several single target gcd being used.
