What size of game are you playing? Six exorcists, six repressors, 6 stormbolter doms is 1830pts...two HQ cannonesses to make it a legal detachment...
I'll admit I'm not exactly quaking in my boots. It's a lot of infantry clearing power, the girls already do infantry clearing well.
Exorcists seem great on paper but that's a huge points investment. All six shooting at one target will delete something, but positioning all six for LOS is a real pain. And like any long range shooting, they really benefit from a screen. Otherwise those Scouts or Eversor drop in and tie up one or two, maybe even three if they're really clumped together.
3 Exorcists is likely the max (also if using the organ model, 3 is likely the extent you'll want to assemble). 5-6 Repressors could work, but maybe a 3 of them with melta doms, 3 with stormbolters. Gives some points for Celestine, maybe some melta pistol Seraphim.
I'll be working towards more varied lists eventually but I'm starting out with a mobile pill box theme. The points level is around 2k. I was thinking about dropping the Exorcists down to 3-4 but for their cost they are really quite good. They got almost a 30 point reduction with CA.
Yeah there is a ton of infantry clearing potential with all the storm bolters. But I figured that the six Exorcists and 12 hunter killer missiles should be able to take out most of the big threats that Storm Bolters would not be able to. I don't only have the Dominions, I have some troop choices in the Repressors as well. I was mainly trying to feel out if people thought bringing in that much firepower in decently hard to crack Rhino Chassis would be viewed as bad form.
I personally find exorcists to be deeply disappointing. They do an okay amount of damage over the course of a game and camp objectives fairly well, but they just don't do enough. They're too random, too command point hungry, and too easy to shut down. Every point of an SoB list has to be carrying as much weight as possible, taking exorcists gives an opponent clear things they can ignore. They can gamble on a bad turn of exorcist shooting and have a decent chance of not being punished for it, which would be devastating to your dominions.
As for using exorcists to clear the big stuff? Eh...probably not? An exorcist does 3 damage on average to a T7 vehicle without an invul or cover and right around 2 damage per turn to a T8 vehicle of the same. If you run up against something like a plagueburst crawler or even a leman russ in cover(which is hard but doable) , you're looking at less than 2 damage per turn. With 6 exorcists over 5 turns you're likely hitting the statistical average so...maybe 18 damage per turn for 810pts? To put that in perspective a squad of melta-dominions does right around 9 for 137 and a Stormraven does 10 for 358. The hunter killer missiles will do 12 damage on average in a game, again to t7 and a 3+ save. Exorcists are okay, but index armies don't really have room for 'okay' atm.
Finally, worrying about 'bad form' as an index army is silly. We don't have dark reapers or flyrants or infinite cultist, or infinite poxwalkers, or 8 darktalons. We have melta, bolter, flamer. Do what ya want. If someone gets offended that scrub should git gud.
