Here is my feed back on this new addition.
Things I liked: Evasion skill(Simple and makes sense), Psyker Powers(at least when compared to Dark Heresy 1st ed). Beginning Affiliations (I like the idea of maybe being an Adept working for the Adeptus Arbites and other possibilities.)
Things I do not like: Lack of Lore Skills(I liked having different Ordos with different specialties), AP System(totally did not expect a whole new system, was hoping it would just be closer to Only War or other 40k products. I mix them a lot and there is no way I am buying all of those books again once you start going into Rogue Trader 2nd ect, and I do not buy that you will not do that if people start to go for this new system it is inevitable) Generic Class Names (Mystic- Sounds like a Heretical Sorcerer to me, Warrior- Is this a Fantasy Game? 40k has some very unique and very Iconic characters and these did not fit the bill.)
Will I be buying this? No. I had hoped for more of a 1.5 than a 2.0 I guess. My suggestion, do not fix what isn't broken, focus on making Dark Heresy closer to Deathwatch, Rogue Trader, and later 40k RPG products and you would have my money...again.
