Character Completionist?

[Confessor]

For my main group who consisted of Terra, Sabin, Edgar, and Mog; I'd level them to the highest and have them learn all of the spells they could. Next I'd put together Celes, Locke, Relm, Setzer and level them to about mid 70s and then drop them completely. Then Gau, the strange fellow from the Zone Eater, The old man, and Shadow for them they'd be in mid 60 or early 70s. The main party was the one I focused on while everyone else was on the back burner until the final dungeon.
