As a 15 year veteran of the Sororitas, I've been slow, very slow, to give the recent slew of new models any real thought. But since they're being followed by a new codex, I'm more or less forced to give them a second look, since that codex is written in the context that those units are a "thing" and Nottingham wants very desperately to sell that new plastic to recalcitrant anachronists such as myself.
I'm thinking the just-announced Abbess Sanctorum will be similar to the Silent King in a way. She'll be cheaper and more fragile, sure. But I'm guessing that fielding her will more or less dictate your army list and play style in the same way that the Silent King does. If so, I'm not interested, there will be plenty of room to build a competitive list without those limitations.
The auto-tapestry seems very interesting. It probably isn't going to be viable unless you're fielding a horde of infantry, but that is sort of my play style when it comes to SoB. The question is going to be whether it's suited for just locking down a table quarter with a couple squads, or whether you have to blob up 2000 points around it to make it worthwhile. Toughness 3 suggests the former in terms of points cost, in which case I'm all over this unit. I am very curious to learn the effects of the accompanying remembrancer. Maybe more impactful in a crusade setting?
I still feel like the idea of the dogmata is bad. I know there are plenty of self-interested, empire building careerist charlatans in the ecclesiarchy, but the "need" for dogmata suggests that those frauds are the rule, note the exception, and that's offensive to me. Still, I think that the unit is going to be critical in terms of providing toned down and distributed auto-tapestry buffs, and Dolan can only be in one place at a time. Dogmata may even be good enough that you don't actually NEED the auto-tapestry.
Palatines...yeah, sure, lieutenants with boob armor. I don't field one in my Dark Angels list, and probably won't see the value to my Sisters, either. *Maybe* if they're HQ, they're the cheapest HQ, and I can't get two HQ choices that are actually worthwhile. But I suspect that I'll be running Celestine and a Canoness (aka Mother Francess).
Sacresants still disturb me. Despite being T3, I have to assume they have two wounds, and with those shields, they probably cost too much to be worthwhile, sort of like 8th edition Lychguard. And they also alter the long-standing tradition that sisters melee units have enormous offensive potential, but just aren't survivable. They're supposed to die in atonement for their sins, sooner rather than later, whether or not they take any of th'emprah's enemies with them. Melee troops that are supposed to dish out a beating and still be on the table at the end of the game just don't compute. But who knows? Maybe in terms of gameplay, they'll be the bee's knees. I do like the look of the ones with maces (but not the halberdiers), except for the crap built up on top of their backpacks, but that's what a hobby knife is for...
Paragons are hideous. There's no way around that. The way they did the arms works for me, but the legs? Doesn't work. They're probably going to be good on the tabletop, though, if they aren't overcosted. By "good," I mean fast enough to be prime multimelta platforms. Coming in squadrons of three or more, that's enough melta fire concentrated in one unit to be dangerous, and they're probably going to have decent speed to get those 6+ shots into range before they themselves die. Flamer and bolter versions are probably utterly useless, though, and the melee weapons at best discourage charges, I can't imagine they're going to be the reason to field this unit. I'd say that flamers and swords would be decent against hordes, but this is an army that doesn't need help in that department.
Castigators seem like leman russes in rhino hulls. Except that the big gun is probably less capable than the real McCoy? Less durable and less smit-ey? It's a capability we didn't have before, but I'm not sure it's one that we need. Maybe I've just done without proper tanks so long that I've outgrown the desire? Either way, I can't see them displacing my exorcists.
I guess I'll be enlisting some dogmata, maybe the banna wava in chief. Probably antitank paragons. But probably not the pseudo-preds, lieutenants, lychguard, and Abbess. And I'm deeply concerned that the new codex will gut the Triumph, given that GW's sales of the model have almost certainly reached market saturation. And I'm super excited that I will be able to build Minoris Convictions around the Order of the Mourning Rose.
