As for the holy trinity, they usually aren't a class in of themselves. There will be several classes that can perform each role, each in their own way. For example, one class might do high damage by summoning and using destructive magic, while another might sneak around with two daggers, stabbing the enemy in the back. However, ZOS has said that the holy trinity would not be as prominent as it was in most other MMOs. Most people will likely be a combination if two or more holy trinity roles.
