I have not found a PUG yet that has been able to take down Garuda EX let alone Titan or Ifrit. Otherwise, yeah, that Primal Extreme axe would probably be my first one. On the off chance that my FC would be able to help me with titan on WAR, I'm almost worried about being a liability due to low dps from having a DL weapon. But on Balmung, if you don't have at least an i70 weapon, few people will allow you into a group for Titan HM.
