Sure. But I also noticed that the "flawed PCs" that people tends to make are dumb fighters, weak wizards etc. I've never seen weak, sickly fighter or a stupid wizard. The flaws that people chooses for their character (if given a choice) are always ones that has a minimal impact on their performance in their chosen field.
Exactly.
Even in pre 3e, the game wouldn't allow for low STR fighters since you needed a minimum STR of 9 to qualify for the class.
