What do you think is the 'ideal level' for an established character? By that I mean when do you think it is appropriate to start heading off on the major quest lines (Daedric, Guilds, DLC, MQ, etc)? I usually wait until level 10, but my level 28 Dunmer Assassin hasn't touched a single major quest in the game (waiting till level 46 to get Nightingale).
I know it's just opinion and could vary from person to person, but I just don't feel 'right' when you immediately start doing Companions on level 1-4.
