The Fallon's a fun concept, divergence is good, and a lone wolf/possessed hybrid in a sisters-esque army drives the point home. One random suggestion, perhaps have the fluff mention the Inquisitors involved state that researching the Fallon is crucial to "The Exorcist Project", as a small way of tying them into the 40k universe as a whole (I doubt the Inquisition attempted to make the Exorcist chapter without going through any prototypes/research). Although, I would recommend dropping wounds down to 2 (a la the Lone Wolf), 3 seems a bit much for the fluff.
Then again, since they pretty much have to walk to the enemy if they don't roll infiltrate, and are tugged around by Rage, this would be a very tricky unit to use, and has a pretty high likelihood of being shot up quickly, 3 wounds or not. Having infiltrate standard would help with that, but does start to encroach on the Lone Wolf - maybe she naturally has deep strike? (Perhaps the Fallon are intense enough to just jump from a low-flying drop ship - alternatively, grav-chutes.) Alternatively, the loss of rage and having fleet/12" charge standard could also solve the issue.
Personally, I've never been a fan of random-ability assignment. It just strikes me as pretty arbitrary - in "reality", would the abilities of a possessed/fallon really be so unpredictable? Sure, the commander would have little control over what abilities they have upon their creation, but they would know their skills prior to the battle, and potentially have the opportunity to request one meeting certain requirements. In the game of 40k, there's no representation of the random nature of supplies during in a war - the fluff can go on and on about rare, hard to maintain archeotech, but that doesn't stop the Imp. Guard from having three plasma guns in every squad, or triple exorcists among sisters etc. I'm just not sure why the random nature of supply is ignored, but the random nature of past magical influence isn't. As long as all options are equal in value, allowing the player to select (think Imp. Guard Stormtrooper missions) shouldn't be an issue.
Back to the deployment/rage issues of the Fallon, it reminded me of a few thoughts I'd had on the Eversor a while back. Fluffwise, those assassins are deployed via 1-man drop-pod in which they're kept in stasis until shortly before landing. I'd mocked up a simple concept of how those might work in battle - deploy like a standard drop pod, containing only the Eversor, but when landed, the unit isn't immediately ejected (still being wakened from stasis), but rather disembarks the following turn, at which point they may assault. This would serve the balance purposes of giving the opponent some chance to react, but not leaving a squishy assault unit out in the open, vulnerable to the opponent's fire. This concept could potentially work out nicely for the Fallon, and would support their image of doomed-to-die warriors - being fired in a drop pod into an area heavy with the enemy.
I'm very much into the concept of the unit as a whole, it makes sense for the army and provides a form of support that standard Sisters don't have in a way they would never attempt to provide such support. Good divergence.Vulture&Salamander
The changes to the Vulture load-out work out pretty well, since they've lost the ability to achieve atmospheric flight, presumably they don't need to be as lightweight, hence the ability to carry more weapon systems. One note, this would probably be a bit more normal in the IA books than having them squadron with Thunderbolts - it's an oddly written entry, but Imperial Navy support entry in IA1 doesn't allow the selection of squadrons, it just lists all the profiles/options in one entry while only allowing one lone vehicle to be purchased (no idea why, really).
Salamander looks pretty good, I can understand the price drop, the version in IA1 seems overpriced (it's funny how forgeworld units seem to carry a stigma for being "broken" - on the whole, they seem to be overpriced compared to standard codex).Rapier
Unsure on the Rapier though, I think it's worth to play up its role as a piece of artillery, and use the Artillery rules, with it being assigned crew (judging from the images/a short quip in the Apocalypse book noting that it could be counted as an Imp. Guard heavy weapons team, it seems that the sole purpose of it being self-propelled is simply because the weapons mounted on it are just too heavy for the crew to carry). I've been working on a bit of Space Marine codex rewrite, and have worked them in to the Techmarine artillery entry - it just seems like a nice way to use an underused ruleset (are there any artillery models in the game besides those in the Ork, Eldar and standard Space marine armies?). Having them as an addition to a Retributor squad might be a nice way of adding them to the army.
Additionally, the lexicanum mentions it had something in the way of a Machine Spirit targeting capability. I can't really decide between two ways of representing this - either allow it to target a different unit than its squad, or allow it to be an anti-aircraft weapon (ignores flat-out movement saves/turbo-boost saves). I am leaning towards the latter, as that's an angle many armies are weak in.Edit:
Whoops, forgot a few points.Fluff
Small, incidental question, what kind of markings would the Sisters display on their shields? Would veterans have heraldry etc.? (One thought; perhaps the Oblivion Knight has a plain, no heraldry, black shield to emphasize her non-identity).Wargear divergence
One thought on divergent wargear, this one would be pretty invasive throughout the armylist, but how about switching the signature Eccliesarchy Eviscerator for a signature Malleus Thunder Hammer? It would be a slight downgrade vs. vehicles, but making such concessions to the "normal" sisters is a good thing for a divergent codex. It would make some sense (especially if the uncomplicated Eviscerators are produced "in-house" by the Eccliesarchy, not the Mechanicus - not a confirmed peice of fiction, but plausible), and could potentially look pretty cool.
