The skimmer transport hellmobile has av 12 12 11 not 14...it does have machine spirit though.
I don't remember seeing a deep striking land raider but I didn't look that hard.
The codex did not seem super unbalanced...and Im a blood angles player.
Good poop is really expensive.
Death company can take all sorts of stuff again but start at 35 pts per model base with jump pack. (you can have a squad of 30 though

)
Everything costs a good amount of pts.
I think the only really cool thing I saw was that you can take a land raider as a dedicated transport for your troop assult squad

....I think. I would have to look again to make sure.
