I've got the core book on order. My probable next purchase will be Creatures Anathema. My question is whether I need to get the Inquisitor's Handbook at some point?
I'm a "rules light" kind of guy. My general preference is to have a number of generic options that could account for a wide range of specifics, rather than having a rule for each specific thing (i.e., I prefer the option "Soldier" to a number of options like "Soldier: Infantry", "Soldier: MilInt", "Soldier: Scout/Sniper", etc. because I think that how you build your Soldier will basically suggest what your MOS was).
That being said, I have heard that there are a number of new weapons described in the book. Anything that's a "must have" from the perspective of 40K fluff?
Anyway, tell me why I should definitely get this one, or alternatively why I can safely give it a pass.
