My Dark Eldar are also getting reinforcements this year. I've mostly been lacking in Heavy support choices for my army, and I decided that I wanted to add something a little fun into the mix by using a Reaper. With the advent of hull points, the Storm Vortex Projector has only gotten better.
I've got some more painting to do on this yet.
I'm also toying around with putting a couple Storm Vortex Projectors on the Rapier super heavy.
