I'm excited for General Hux as an uber-fleet officer. I was always one to run fleet officer before, and now it just gets sweeter and more far-reaching. A small TIE swarm will be deadly with this ship backing it up.
Also, I picture this running more like a support battleship than a pure support ship. It wants to be in the action and blasting away while handing out focus to its friends. As long as the dial has one white turn...
