The forum seems to have issues again...
"Oh wait, so the novels are a valid source now? But only when they back you up...?"
If you cannot resist flaming instead of ignoring me as you once wanted I would greatly appreciate the effort of at least reading the entire conversation before posting.
"In the old Inquisitor book Space Marine armour provides more protection and comes with a number of built in systems that 'civilian' power armour (remember that YOU keep using that word, not us). Not to mention that Space Marines also had a Toughness at least twice that of a normal human, and strength 4-5 times their. How's that for "official" GW fluff?"
Oh, suddenly that stuff counts in your eyes, yes? Does that also include the bolt weapon stats which were identical for both Space Marines and everyone else?
The "Inquisitor" rules make no difference between different kinds of power armour such as Light or Heavy variants, and Non-Marine versions that have indeed officially been described in fluff texts as possessing an equal armoured protection do not appear at all, so what exactly are you referring to? That is neither new information nor does it retcon anything.
Oh, and the 'civilian' term for equipment is not something I came up with, by the way. It was introduced by the Black Industries authors to distinguish between stuff used by Spess Mehreens and everyone else. That it only popped up once doesn't change that - in the eyes of some - there seems to be something inherently wrong about how that particular writer perceived the setting.
"Oh, and there IS 'official GW fluff' backing this up, if you really insist on relying on something that doesn't exist, because there's absolutely no tiers of officialness like there are with other settings' IP."
Tell that to George Mann, Head of GW Publishing. He seems to think differently. Gav Thorpe also had a blog entry where he talked about the various "interpretations" of the setting and had drawn a clear line between BL and Studio works: http://mechanicalhamster.wordpress.com/2010/01/21/jumping-the-fence/
Here's something interesting, too; this very RPG franchise gets mentioned as well:

Scroll to post #5 - though the entire thread there seems worthwhile reading and somewhat eye-opening for all of us (yes, myself included).

"Are you saying that inquisitors can't move if they wear a power armor!?"
Ah, that part of the discussion was referring to Astartes armour, which (probably) lacks the conventional standard interface in favor of connecting directly to the Black Carapace in the Marine's back. Given that an Inquisitor doesn't have something like that, modifications would be in order to make the suit work. We were or are merely in discord as to whether such modifications can be done or not.
