Personally, I loved the party you got right before taking on the final boss.
I think it's the best party you could ever think of in this game.
I mean, we've got the strong main character Cecil, the equally strong dragoon Kain, the excellent healer Rosa,
the überpowered Black Wizard/Summoner Rydia and Edge, the combination of a thief, monk and ninja.
I love this party, it feels so incredibly well balanced, and I doubt you could get anything better.
