But I guess the more important thing is that the Traits are defined in detail on Page 7 during Character Creation, mentioned in slightly different detail on Page 12 for the Solo roll, and then only referred to on page 15 for the Build-Up roll.
I feel like there's consistency missing there, and instead of adding more text to page 15, I think it would be better to have Page 12 refer to Traits in the same fashion as page 15 while having them completely defined on page 7. This way, players only have one page to go looking for when we can't quite remember what the Traits cover.
