I never understadn why there aren't Sword&Shield version for Ifrit/Garuda/Titan/Moogle. Only Leviathan in ahead have it. It was a bit weird when you got the shield titan on 2.0, but you have to go with Garuda or Ifrit sword because wasn't a sword version of Titan.

They added a DRK, MCH, AST weapons to old primals on 3.0, but didn't add the miss weapons/shield for PLD.
