Yes, but as i said, every player would be a specialist, when you only need a 8/8 skillcombo. And if you say they need a skillcombo of 15/15 where's the point in boosting them even more?
The main issue is, that i don't think it's even close to possible to implement a flexible or fluid system, in which you get special attributes by the players skill set. It's not even possible to provide the players with individualized birthdays. By the way, THIS would be a nice new feature.
