Dude, they're for Farmers, Merchants, and other people who only need skill ranks making opposed rolls (or reminding the DM roughly how good they are at the few things they do). A PC should never, ever, end up with Ordinary levels - Player Characters are extraordinary by definition.I haven't read True 20. But, for me, levels that aren't really levels (i.e. they don't provide anything beyond skill points and/or feats) are an obvious design error. If these character features are meant to be available without levels, then they should be designed that way.
A design error is an intentional choice that fails of its goal(s). The Ordinary role was a brilliant design choice that perfectly achieved its goals.
