Awwwww no Wizzy love? They can solo, port and sit on their butts just like a druid! If you want a real challenge, try one.

Necros are a good "afk-class" as well. Find a single camp where its safe to afk after u kill mob. Come back when it spawns again. Easy peacy.

Fearkiting is easy and safe and after 49 you'll be able to root rot all day long.
