I wouldn't have minded having to play the Water Shrine battle with just Dagger and Eiko; with those two in your party you're frickin' invincible; they're like Red Mages who can't equip any decent weapons. I love them!

I think Vivi sucks. You spend the whole game making him learn spells, of which about two are useful at the end, and even if you get Firaga, Dagger can summon Ifrit for slightly less MP, with no damage penalty for splitting it across all enemies, plus she can heal.

And his ultimate attack is a joke.
