I was lax in my point. In Thunder magic I was thinking in regards to special tomes or a special tome. In 3-2, I believe, it's possible to steal a Bolting which has a Wt of 19. And I personally always aim for it. A Sage Ilyana with 9 Str would suffer hinderance. Though in one example, I realize that Str is not that important for mages. In the case of stealing Bolting for Ilyana, having good Str growths could help. But yeah, I'm not overly concerned or anything. The main issue with mages it seems is their Spd.
