What's depressing about the 8HP limit is that Chaos fleets cannot have any cruisers to benefit from Battle Brothers or Sector Allies. With only Orks as their BB (fitting, mind), and all Ork Kroozers being 10HP...sadz.
In fact, Chaos gets almost nothing out of the rules. The lance upgrade only affects Idolators, and everything else only benefits from the ignoring blast markers. Poo.
Okay, so regular fighters become Resilient, and Resilient Fighters are changed to a 2+/4+.
I hope these are in use next year too when I use Imperials, because Thunderhawks/Eldar Fighters are going to be damn hard to shift with AC.
