Look for other games that have more racial limits. I read somewhere using a zero racial points, and at least one advanced trait is a real challnge. Other options would be to put design limits like "none over 120, none under 80" and flexability would be determined by the starting points you get. KOTH is just type of game. If it does not suit your taste in game play, don't play it. If you want to test your metal against a 125/125 bezerker, join in and give it your best shot. That goes for any MP competition. When you have games like SEIV and Stars! that have a very wide choice of race settings, your going to have a wide variety of challanges available. An unlimited settings game is not any more wrong or right than a limited settings game.
Don't get wrong, I can certainly understand your frustration and POV. Perhaps what is needed is more of a variety of restricted settings games. I am not playing any PBW games yet, so I don't the make-up of the majority of available games. You could always host one yourself, and set it up anyway you like.
