1.) Is a party composed of mageknights good?

Insert any frontliner class here + Insert any magic user / Insert any color, noun here + Mage
(assume everyone has Dual Wield, except the Bishop and the Mog Knight)
Ex: Paladin + Black Mage, Soldier + Black Mage, Blue Mage + Fighter, Bishop + Defender, Chocobo Knight + Mog Knight, etc etc.

2.) What happens if you complete the game in FFTA2? Will you be given a Judge Sword or something?

3.) Someone told me that Seer/Illusionist is the most powerful in game... Is a Red Mage + Summoner + Turbo MP and Double Cast combined + any form of MP restore without using items like Choco Recharge, Ether Cannon, Mantra Magik a good thing or very risky?
