So we know we won't directly chose to be a warrior, spellsword, bard, rogue, etc. No problem. However, it would be nice if based on how we improve skills, the game would calculate what class the player character is at any moment. Maybe NPCs would even comment appropriately, "I'm guessing you are an aspiring battlemage." or later in the game, "that looks like one tough healer." We know this would be easy, because the Oblivion intro already had Baurus guess the player's class before it is chosen. The main difference would be that the class would be forever malleable until the player nears a level cap.
