This is super cool but I think some of these aren't correct unless I'm misunderstanding. In order to specialize you must expend a third die.
Investigator adds up to 7 points; The Daredevil has 8 points but it states expertise: Cars, Planes, Choppers (don't you have to pick ONE?); Medic also adds up to 7 points.
Sorry if I'm misunderstanding this!
