I have two characters, obviously, and I love playing both of them and leveling both of them up, including sub-classes~! I have them in different cities so I can see the story line to that city.

I don't think there is any wrong or right way to play this game if the person is enjoying it. I mean what is the point of SE giving me 40 characters if I don't use them, heehee. And for people to say if they have more than one character they are wrong, or don't understand the game, well that's just sad. People shouldn't be putting down other people for how they choose to play their game and their character(s).

It's a personal preference and has nothing to do with wrong or right. I know a lot of people who play two characters, actually!
