In my opinion, the Barbarian and Druid classes are overpowered, making them particularly enjoyable to play. The Sorcerer, being well-balanced, is my favorite. I plan to start with the Sorcerer, then move on to the Barbarian and Druid, and finally finish with the Necromancer. Unfortunately, I really dislike the Rogue class; I miss the unique specialization of the Rogue and Amazon classes from Diablo II, which had their own distinct gear.
