in the video it was explained that only one thing is exclusive to the classes and that is their skill line, which was done because the developers wanted each players ability to complement anothers, which promotes the multiplayer aspect of the game, which is the first time this has been done in an elder scrolls game. other than that, everything else is up to the player's decision, which includes weapons, armor, magic, etc.. as well as other skill lines that can be aquired through quest lines or joining a faction like the mages guild or fighters guild.
