1. Depends. The cheapest I saw is 4 mil.
2. You also can do gathering. (Crafting was supposed above)
3. People say here about undersized party option when you retain your leves and skills but dont get experience for dungeons. Actual runs require party, arcanist evolve into DD or Healer.
4. Raiding or fighting "gods of random" in diadem(added in patch 3.1).
5. 3\10 I suppose. Depends on how to scale it.
