Probably not the response you're looking for, but I'd happily "demote" barbarian from class to background (or maybe race?) Make "Brute" or "Rager" some kinda fighter subclass if needed.
Of course, I'm also of the line of thought that Ranger and Paladin could/should have been Fighter subclasses as well. So I'm a bit of an outlier in this regard.
Not too much of an outlier, as I would do the same. Especially for barbarian. That's a cultural background, not a primary occupation. I mean, we don't have a class for "civilized urbanite" do we? The class never sat well with me for this reason. Also a reason why I liked the 2e Complete barbarian's Guide because it illustrates how many of the "barbarian" cultures had nothing to do with raging.
