This is irrelevant to FF7 per se, but:

If you paid attention to my 'Omega weapon is teh suxors' response where I said that Rinoa and Selphie were worthless people because they didn't have good attacks, you'll realise that I had no idea what spells Rinoa really had.

So even if you have every character it doesn't mean that the character will be used. I typically don't do anything with any character that's female in FF8. The only reason Quistis has all her blue magic was because of her degenerator spell which I used to defeat malboros (and thus leveled up Quistis and cared about her limit breaks).

Pah.
