As a silly newbie, I have a question about other classes and which ones my wife should level in order to improve her Gladiator in a duo and/or team environment (her duo partner (my character) is primarily a Conjurer).

In your opinions, which other classes should I also be leveling in order to improve her experience with her Gladiator? What are the desirable abilities from the other classes and what level do those classes get them? (I'd appreciate being told why these other classes and abilities are useful as well.)





(Other advice, suggestions and/or pointers to working and updated reference sites would be appreciated as well.)
