Dainn > Eir > Sieg > Krieg > Yuki > Lime > Tia > Dacy
My preferred party is generally two Siegs, An Eir and a Dainn. I've done a lot of parties with this setup (With people who know how to play their class) and it works flawlessly. Regardless of class though, I do just prefer people who know what they are doing and respond to voice commands.
"There once was a boy who dreamed of being a hero. Who believed sincerely in the battle to banish darkness from a world of light... but light and darkness are equal... and where one exists so too must the other... and when the boy finally realized this he had taken the first step toward being a true hero."
