4 Characters pr. account?

Hello, I just bought the (excellent so far) game yesterday. One thing that struck me at once was that it says that you can have 4 characters as a maximum per account. Can this be true? I mean, there is 6 classes, and although you can dual-class how can you experience all six classes individually

i agree i dont like this i want one of each class so i can really experience this game, its not like you can just join another server and have more characters =/ even diablo 2 had more then this. I hope they look into this.

i guess theres the chance they'll increase this with expansions. I'd like one slot per class, because although the only difference is that a seconday proffession doesnt get their 'primary attribute', i'd still like to experiment with the primary attribute of all 6 classes instead of just 4
