I find it interesting that Marle has been mentioned a few times. I found most characters in this game to have strengths and weakness that come down to personal preference, but I always considered Marle to be by far the weakest out of the cast.

She is weak in physical and magical damage. I know she is supposed to be seen as a primary healer, but her lack of AoE healing spells places here behind healers like Frog and Robo, who offer so much more in other areas.
