I'm not saying it a disadvantage in character, it's a disadvantage because it's less cool.Also, it's fun to have the reveal of a character's NP that you didn't know about. Cao Cao's, for example, could be rather amusing to happen out of nowhere and surprise you.

Same could be said for skills, stats, and identities. I'd rather keep everything on a level playing field, meta-game wise, and it's a bit late to go for 'PM all Servant bios to me'. :P
