Let's get the bad out of the way. Maybe not so much bad, as missing:
The nice new Hydra kit has lame rules. Giving it interceptor would have made it too powerful for the points, but not being able turn off Skyfire to shoot at ground targets is dumb. As is the loss of it's auto-targeting systems to deny bikes and skimmers their jink save.
I am in favor of the cost increase and carrying decrease of the Vendetta, it was far too cheap and good. The changes to the Stormtroopers (aside from the name change) and the new models make me very happy.
I'm sure something else will jump out and surprise me after a few games, but overall I'm happy with the minor rule tweaks. I really like the new and useful orders and the flexibility of where you can attach your Commissars.
