In Diablo 2 every class had a set gender, and in Diablo 3, while you can change your gender, there is a "canonical" gender for each of the class stories:
- The Demon Hunter is Female
- The Wizard is Female
- The Monk is Male
- The Barbarian is Male
- The Witch Doctor is Male
Is there any difference, other than the visuals, of playing against the "proper" gender? Are there any quests, equipment, or even NPC dialog that changes based on this? Or is it just an option available to players who want to play a champion of a certain gender?
