actually I meant see if they can learn more than 8 skills. and what skills can they learn because if they are going to learn status skills then its no help. when they go to learn the 9th skill it will ask you to choose a skill to forget.
as you were saying not all skills can do that and it completely random what you get so that would probaly not help.
it might be easier to refuse those persona with keeping in mind what skills you want to keep out of the final product.
