Is there any advantage to leveling more than one character of the same class in Diablo 3?
Solution 1:
With the advent of the new skills system that allows such easy respeccing, the only strict advantages are purely cosmetic ones:
- you can then have max levels of both male and female character models, and
- you get the achievement.
Other than that, any other differences would all be self set, i.e. attempting to level by only shooting Magic Missile at the darkness, etc.
Solution 2:
Another advantage is that it's also a way to experience normal and hardcore mode with the same class
