No fantasy RPG is truly complete without a gruff, amusing, down-to-earth dwarven companion. I would definitely love to have more "uplifting" characters that are there to help your guy, that makes you in turn want to help them, as opposed to being forced to keep company with a bunch of whiny backstabbers.
Who is whiny? and who is a backstabber? the only two characters who fit the role of bitchy, or whiny are Shadowheart and Lae. I'd call Lae more straight forward, blunt, conservative and Shadowheart more "guarded" than whiny though. Shadow does more guarding and deflecting, than whining imo. Wyll & Gale are both classically good bro characters, I don't see them ever being whiny.
