If I'm not mistaken, you could start playing assasin or rituatalist from Presearing. So, will there be new quests for them to get skills, or just simply add skill rewards in the old quests? Does anyone know?
When you make a new Charecter you have the option of whch campaign to play before picking your profession. I assume that if you play the Prophecies Campaign and are allowed to take an Assassin or Ritualist they will have there own quests in Pre-Sear.
