>>> The problem with Kimahri is that he have to wait for an overdrive to cast one blue magic.. Besides that, he was a cool character.

About the other

FF5 Blue M: I never used them much. I only liked the "Aqua Rake" spell..

Quina: Now we are talking, I have never used a Blue mage so much in any other FF. I could spam 9999 non-elemental damage with limit glove over and over. It saved my ass many times.

Strago: Never used him, there were way too many playable characters in this game..

Quistis Trepe: Same as Strago, I just used her when I had to.. Never cared much about Quistis..
