FF 1 - Fighter/Fighter/Fighter/Fighter because apperently that makes the game super easy. (never beat FF 1, to archaic feeling, but this is what I'd do.)

So.... Fifth fighter.


FF VI - Sabin/Edgar/Terra/ and my fourth was never consistant. Probalby Strago.

FF VII - Cloud, Cid, Barret. Throw in Red cause PUPPY!

FF IX - Zidane/Vivi/Amarent/Garnet

With this though, Probably drop Garnet and put in Freya and Quina. Plenty of Healling with the supports of this group, and a lot more offense and utility available.
