Generally, any characters with a range of powerful abilities will be limited -- we try to leave the sort of limitation up to the player, but the model you proposed would be acceptable in the sense of choosing physical prowess vs magical prowess.

So for example, a character who is known for their connection powerful spiritual creatures but also known for their ability to cast powerful magic might fall under shaman and mage -- the player would then choose which school they would prefer to focus on, and then have the alternative be much harder to master.
