Hello!
I did a quick search and didn't see this one come up. I just started a new game with a rogue and got to level two. Looking at the skills that were available to choose from it looked like I had was able to choose from all the skills available to all the classes. For example, I had about 15 skills available under the class tab rather than just Backstab.
I haven't played for a while but I don't remember having that many choices the first time around, so is this how it's supposed to be?
