If anyone has checked out the new Chaos Codex, you'll have probably noticed one thing: the points got a lot
cheaper. Watch this review if you're interested:https://www.youtube.com/watch?v=wQa-to_os94
Loads of weapons and units saw huge reductions in points costs- several weapons getting 50% or 75% cheaper, and some units getting close to 100 points slashed from their costs. Some of these changes are huge, and have absolutely given new life to units such as Defilers, Daemon Princes, and Heldrakes.
Whatever method Games Workshop uses to define points costs, it might be the case that other armies too will see reductions in points. In the Chaos book, seeing formerly bizarrely-expensive upgrades and units drop to much more reasonable points costs makes me think about Broadsides and XV8s!
