I've had Hectors with super high STR and low everything else, or Sains with that issue. I like my units somewhat balanced. (LOL, Raven does grow like a myrmidon at times.)

I remember my first few games I failed to use her and then suddenly I was like I CANNOT GO A GAME WITHOUT THIS CHICK. She, Lucius, Serra, Priscilla, Florina, Nino and Oswin are my "cannot go a game without" people. Canas might make that list, too, he's being a total badass.
