Sure, you can make up your own, but that increases the ability to power-game. Now you can choose abilities that you know you'll be good in, as opposed to getting only a partial match.
Power-gaming isn't about avoiding trap options. That's just normal play, nobody wants to get suckered into options that look good for what you want to do, but really aren't. Power-gaming is about being the best at whatever it is you want to do. Flexibility and versatility in options makes that easier not the other way around.
