I'm right to say that minimal or exceptional doesn't change a thing during the game ? If yes, the only importance would be the taping speciality as it's not influenced by the level.
the level change a lot, taping doctors can just "repair" players with a one game injury. With a high level doctor is much higher that it is just a game injury, compared to a doctor with minmal level even when the chanche is the same to repair when it is a one game injury.
But i highly doubt that nt have taping speciality.
