This is the current build I am running while leveling. I am currently lvl 30 and so far really like this build. In the beta I experimented with the different classes and found out that I really enjoyed the archer, defense, occultism, and vitality.

Armor:
I mainly am using Cloth with the 4 set bonus but I plan to try and go after more plate with intelligence on it later on.

Weapon:
Staff and Bow. I might change and use a shield at end game if I want to be more tanky.

Rotation:
I always open up with this combo (, , , ) and usually they are dead before they reach me but if they do I just kite them with and the , combo.

, , , , , , is another useful combo train. I just initiate the battle by ranged first.

Use , to help heal.

and are great buffs.

Let me know in the comments if you try this build out and what you think about it.
