I'll agree that players with similar levels of System Mastery will tend to create characters that don't overshadow each other... but in part that's because they will skip 'underpowered' options entirely, so they might not have to worry about Fighter vs. Wizard because none of them ever take more than 2 levels of Fighter.

I have seen players that often visit char-op boards and come up with characters, that should be broken but altogether fail when introduced to actual adventuring. There is a difference between system mastery and alleged system mastery.
