@Communist Starlight They seem to do a lot. You can kit them out for ranged or melee combat. I guess they can also be a big distraction piece ("distraction carnifex" is a term I've heard in the community).
The big changes were to how some secondaries are scored and player two's turn five scoring. However, there's also some points changes for Orks and 'Nids and some nerfs to Space Marines. It might mean that your boys have an easier time against those Space Wolves.
@Nittany Discord Ooh, eradicators getting nerfed and KFF getting buffed really does help out. I might be able to fit in Nobz now. I did play the game, I got wiped but I was very close to winning. I forced the wolves to play in ways they would not have normally played. I am worried about the infiltrators though, because they can reduce the damage they take.
Also, my Tyranids may or may not be fighting some Eldar or Imperial Guard tomorrow. My roommate's friend is coming over for a 40k 1000pt game. I'll probably let my roommate play against his friend, but you never know.
