All right, many of us were disappointed in the Battle Sister Codex. Crud messed us up. I was thinking of forming a little thread, and, like the Eldar, see if we can come up with an interesting 5th Ed Codex. The one we have now is...dry...to say the least. I want to go hog-wild with the fun rules, but I think we should focus on taking base list and adjusting it by the minimum to bring it up to par. Consider baking a good cake before adding the dressing. I figure we can start with the HQs and Acts of Faith and move down. 40k, after all is often about the heroes. Once we get HQ down, we can move down the list to Elites.
Acts of Faith: They need to scale, and it should not be complicated, more so considering how unreliable they usually are. 1d6+1 per 500 points seems reasonable enough for me. At 1,500 this gives us a swing of 4-10 Faith Points.
As for Sisters forgetting their previous Acts as they get promoted, have Light of the Emperor be available to every squad, have Celestines be able to pick one additional Act from the Retributers, Dominions, or Seraphem, to represent their previous position (Thus, giving them Light, Hand, and one of their choice). Give the Command Squad the same choice, but add the Celestine's Act onto the list. The Canoness gets to pick one additional Act from any squad type. Thus, the basic BSS gets one Act, the Seraphem, Retributers, and Dominions get two, and the elite Command, Celestines, and Canoness get three.
Saint Celestine
Way undercosted. An Archon with Agaonizer and Shadowfield costs about the same, but the Living Saint comes back from the dead, is almost as durable, and has a Jump Pack and Heavy Flamer. Her rules are fine as is, as I think Living Saints should be awesome. I see them being almost the Imperium's version of a Deamon Prince, being exalted by a god, and thus, raised up high. We just need to adjust her price a bit. I would say adding 25 points to her cost might even things out a bit.
Canoness
Poor girl. She got slapped hard with the nerf bat. To start, I would give her a free Rosarius, and open up the option to buy a Jump Pack and a Blessed Weapon.
Sororitas Command Squad
Let them buy more members at the price of a normal Celestine. Give the option to take Evicerators and Power Swords.
Confessor
Drop him to 55 points base.
Conclave
Its fine.
Kyrinov
Fine as is.
Jacobus
Fine as is.
