I actually think they should just have you choose what you want to play when you log in. Structured PvP, where you just have a PvP name that you use. You choose your race, profession, load it up with skills, and get into a game. At the end of the game, you can change your race, profession, and skills in the equip menu. Or the PvE area. Where you have personal story, dynamic events, dungeons, activities, WvW, etc.
