Having two classes gives you many more options character-wise and that is very good, as the system will not feel so class-based when there are many, many variations (81!) and therefore lots of "subclasses."
Hopefully, they'll also make the game forgiving enough that having a "fun" combination doesn't make you a liability. Some powergamers are inevitable (i.e., folks that will only accept the 4 "best" combinations), but I hope kind of thing can be limited.
I'm not a power gamer by any stretch of the imagination, but I have played games before where you just plain couldn't do certain things class and race-wise, and still play the game the way it was meant to be played.
