Really, given that we've said a half dozen times now that you don't miss anything by taking a paragon path the people saying "but what if I don't want to take one, then I'd be underpowered!" sound like a 3.x person saying "but what if I don't want to take any feats, then I'd be underpowered!" Well duh, if you purposefully avoid taking one of the basic parts of your class then yes you'll be underpowered. I imagine there will be at least one PP you can find for your character that has abilities that will appeal to you, and unless you're the least creative person ever/your DM is a major dillhole, you can easily change the flavor to fit your character.
