There are a lot of Char Op minmaxed builds that do not revolve around combat. Bards with +40 in diplomacy, unbeteable stealth detectors or whatever. There are minmaxed all-around builds too. Anything you try to acomplish can be done better or worse, and thus can be maximized. Sure, you dont need to follow this optimization, but you dont have to in videogames either. And it will be there for anything with high enough audience, including RPG. There ARE forums to minmax the chance to win in rock, scissors, paper game. Which you have to read if you want to have any chance in the world championship (yes, there is one), and you can safely ignore in more casual friendly games. ;-)
