I don't really see the benefit to allowing people to start old. At most, instead of a drop-down menu of 3 choices, we could have a fill-in box where people can manually put in an age of, so, 16-30 (or keep it 17-25). I think older ages are kind of a vanity reward, I wouldn't want to see people start characters at 100 years old, especially now that there's no penalty for it.
Also regarding that, since there's no longer any drawbacks to creating old characters, I'd have all starting characters have the "young" skill set. Choosing experienced used to mean "more reward now, less time to enjoy it", but that's no longer the case.
