I used the option off the Main Menu of the builder, "Build a Custom D&D Character," then selected the "War of Everlasting Darkness" Campaign setting option.
I noticed that the builder doesn't let me choose lots of things like at-will, encounter, and daily powers. It only lets me choose utility powers. For instance, if I roll a Ranger (Hunter), it chooses all of the class at-will, encounter, and daily powers for me. There's no option to choose my own powers if I prefer Twin Strike or such. It only lets me choose things like archery style, wilderness knacks, aspects, lothtouched, and utility powers.
Just to clarify: Am I restricted to choices in character gen that come from the 6 books plus supporting Dragon articles mentioned here (goo.gl/v2Or)? Is that why I'm not able to select my own power load-out?
So for example, since something like Martial Power 2 isn't listed in the book list, may I not choose class powers from that source (unless they're also in one of the 6 books/Dragon articles)?
