I've just noticed that the Dark Angels FAQ has been updated on the Games Workshop website (here). The biggest change for my list is the errata to the Powerfield Generator which now reads: “If the bearer is embarked upon a Transport vehicle, the powerfield’s effects only apply to models embarked upon that vehicle”. So, no more super-survivable Landraider which doesn't seem like a particularly bad decision. But... what if the bearer isn't embarked upon a Transport vehicle? What if he stands next to a Landraider (or two...)? Then, reading the rules-as-written the vehicle would have a save, as would any marines inside that vehicle. Hmmmm....
A bit of googling around suggests that this is the general way this is being read. There's a good discussion on the Bolter and Chainsword forum (here) and a suggestion for what sounds like a nice conversion from march10k:
"If the PFG bearer is standing between four land raiders in a parking lot, all of them get the full effect of the 4+ invulnerable save, but as soon as he steps inside one, all of them, including the one he's riding in, lose the save. There's a relatively simple fix for this...put your PFG on a bike behind the land raiders, instead of inside! You heard it here first! ... damage assessment. I'll have to put my PFG-bearing techie on a bike. He'll also be able to repair either of the two tanks that he's following around, but only on a 5+, not the previous 4+. Also, he's at more risk than before, especially from deepstrikers. Countervaling, late-game, his bike makes him an excellent objective-contesting unit. And with T5 and a 2+/4++ save, he's not the most fragile model on the battlefield, single wound be damned."
The downside (apart from the fact that my techmarine is painted and now looks like he needs replacing) is that you no longer benefit from having the techmarine inside the Landraider to extend the range of the PFG to catch multiple units and I'm assuming that this is the purpose to the errata here. But the upside of having some funky modelling to do makes up for this! Here's some inspiration from Warseer, posted by Rich 123:
The other key errata concerns the Standard of Devastation: "Q: The Standard of Devastation states that ‘all friendly Codex: Dark Angels units within 6” of the standard treat their boltguns as Salvo 2/4 weapons’. Which boltguns does this apply to? (p66) A: This applies to the standard boltgun (24”range, S4, AP5, Rapid Fire), twin-linked boltguns on bikes, the bolter component of combi-weapons, and hurricane bolters [my emphasis]." Good news, mainly because I didn't like the feeling that I might be playing this incorrectly.
So, overall not such a bad result from the FAQ. No doubt the PFG-Landraider interface will result in another FAQ at some point but until then I think it's pretty clear what the rules say though it's a shame it wasn't spelt out more exactly.
