Rangers tend to need stealth to some degree as well you know. Wouldn't make very good hunters if their prey could always hear them or see them taking aim, right?

It's not a particularly one-sided ratio. We seem to have nearly as many fighter type characters (4, possibly 5 since I could be miscounting or misinterpreting characters). But mages? Now there's our minority. 2, by my count, so yeah. A good magic related crisis would probably spell our doom since we'd have so few people capable of countering it. :D
