I did wonder about my =I= list. WH without battle sisters. I was thinking that IST were more fluffy, despite the fact that the Adpeta Sororitas were more capable. I was quite happy building my list around a Lady Inquistrix and another Inquistrix (ie her interrogatrix) and their respective retinues. Certainly not the sort of thing to win a competitive battle, but characterful and multi talented enough to be worth fielding in a themed game against some heretics and a bunch of witches.
And of course there are the repentia, death cult assassins and zealots. All good stuff.
Having now read Mr Abnett's Ravenor omnibus I am if anything more content with my =I= list. It fits the Devos IV campaign well. Lady Josephine will be the glue that holds the Imperial forces together. Without her firm direction, I'm sure the DKK would be tempted to make no discrimination between the Loyal (to the emperor) 2nd PDF Regt and the Loyal (to their homeworld) 13th Mech Regt and 99th PDF Regt.
That could provide an interesting possibility. Perhaps the Imperial side has to spend points on having either the Lady Inquisitrix or her Interrogatrix in their force - to keep them in the campaign. If the rebels kill or capture both of them, then the Imperial side is gripped with interia as the commanders of the various forces disagree. I like this idea, but it is a little un military. I'm quite sure that the Departmento Munitorium would make sure that there was a definate command structure in place before even launching their planning phase. I might be able to weave it in as a one game idea somewhere:
There would be a composite force made up of elements of most if not all of the IG/PDF consituant units. And the Interrogatrix would be the glue holding them all together. If the rebel player somehow nutralises the Interrogatrix, the IG player must make an immediate moral check for each force element to represent the units prediliction to follow its own agenda once the imperative of the =I= is removed.
All of a sudden I can see snipers becoming important. Snipers to hunt independant characters and snipers to hunt the other side's snipers (at the minute the Cadian 144th have two special weapon squads of snipers. The 13th Mech have two individuals). I can see that an increase in snipers is on the cards.
So back to Dan Abnett's work - I might be tempted to try Eisenhorn and/or the Gaunt's Ghosts books. I've been through Gunheads, Ice guard, Eldar prophecy and Dark Millenium. All OK. And Sandy Michell's Cain is a hoot. I liked that so much I bought a copy for a chrimbo prezzie for someone.
