While Falcia's stats aren't bad, she splits her damage between both physical and magical. This may not seem a bad thing at first, but late-game it limits her potential with both. She does, however, retain some use due to her fast attacks and true damage which, although minor, can make up for some of what her split focus lost. Falcia is a simple case of not bad, but also not that good.
