DAWN 1.8 has a few notable blind spots in terms of content that exists for one mode of play but not the other, part of the design objective of 1.9 is to "round out" the game and fill in those blind spots. One example of how this is being done is via the example builds, in 1.8 these only exist as examples for combat, but 1.9 will include some sample characters for unstructured play.
