I'm huge in favor of combat balance between PCs.
Not for balancing out of combat against combat power though.
That's almost an entirely different topic. Suffice to say that no game system, however it tries to achieve balance (point buy, skills, classes), allows a character to be maximally good in all aspects of the game. There are always tradeoffs. We can argue over whether for a given system the available tradeoffs are good ones, but that would do nothing to prove that RPG's rules design isn't motivated by resolving the central conflict of role-playing.
No game system ignores balance completely. You don't start GURPS with infinite points to spend. You can't start d20 with a character with the best progression in BAB, all three good saves, the best spell progress, the most and best skill selection, 20's in all attributes, and so forth. In 4e, if you are striker, you can't tread too far into a controller or leaders sphere and do what they do better than they can. And if you can do these things, generally we don't like it, because at some level we recognize that the conflict we were turning to the rules to resolve has now no longer been resolved.
