I've always loved the Lictor model. The whole praying mantis thing it has going on really sets it off for me. It looks brilliant, although this particular release is a little too static compared to previous models. The fluff behind the Lictor is brilliant too and the thought of it lurking in the shadows, colour changing camouflage, poised ready to pounce on its next victim sounds so cool. So whether the Lictor itself is worth it's points or not, or if they need adjusting in the next codex is open to debate. Either way it will find a place in my army regardless.
I also built 2 Ripper Swarms - nothing to harp on about really, they are what they are.
