No its not unreasonable, but this isnt real life...thats the difference. But even at that, you could go and get 100 people and im going to bet that not everyone can do the same things to the same level of achievement either.
Maybe 20 of them are amazing football players, yet out of those 10 15 of them suck at basketball, and then maybe some that are good at football and basketball suck at baseball when those that suck at basketball are good at it. Its just, you arent going to have the same level of talent to the tee.
Whereas in a game like this, you can basically have the same level of talent to the tee. Nothing seperates the characters.
I mean there comes a time when for a game you have to sacrifice having option after option for a quality game. So when it would become a staple that in every rpg from here on out all characters can be the same thing, where does it stop?
Im just old school, and its not like you cant see each aspect of the game when you have restricted skills to certain classes, its just youre going to have it be more unique when so and so character uses this skill being this other guy cant.
I just feel its what makes movies, books, games all go around. If every movie or book or game has every character being able to do the same thing it just makes nothing special anymore, nothing unique.
If im watching Conan The Barbarion and the wizard can go and pick up Conans sword and weild it just as good, and then pass it over to the thief and he can weild it just as good, then whats the point of having Conan anymore, nothing is special about his talents anymore.\
Edit: Btw im loving this game to death for everything else, this is the only downfall in my eyes, just dont want anyone to think im hating on FFXII. I just would of prefered set classes and some skill restrictions.
