[BTSS] How will the changes work?

Lets take a look at the new Acts of Faith.
Canoness: +1 In, Preferred enemy, USR. She is Stubborn, USR.

Command Squad: Relentless, move through cover. USR

Repentia: Get attack even if killed before.

Battle sister: Auto regroup, re-roll failed hits on a 1, shooting or HTH

Celestian: +1 Str., Fearless USR

Dominion Squad: Twin-linked shooting. Not HTH

Seraphim: re-roll any failed to wound shooting. Not HTH

Retributor: Rending USR, shooting not HTH

So what unit is best for the Canoness to join or do we just use Saint Celestine as our HQ?

Command squad can move and fire HW but is 1 MM shoot better than 2 meltagun shots?

If Canoness joins Celestian unit are they Fearless and Stubborn and how would that work?

The way it looks now the best option would be for the Canoness to join a Celestian unit. She would allow the Cele to be In 4 and re-roll failed hit in HTH and they would allow her to be
Str 5 and the unit to be Str. 4.

How is Shield of Faith going to work for Veh.? Move pop smoke you get 4+ cover save, next round you get a 6+ cover save?

New best unit in game, Dominions, set up, scout up to 12" away with 4 MG and TL MM on Immolator than in your turn move 6" get out 2" you will get 1 TW MM shot under 12" for double dice and 4 MG under 6" for double dice. If you do not win roll off to go first than you may now outflank with this unit on turn 2. Big tanks and unit hiding in the back are not safe anymore.

I think command squad will be tempting to take but not sure it will be worth it in long run, even with FNP.

Penitent Engines got a huge bump in the rules and will be very playable if they can still be taken in squads.

Just trying to find some good in all the cr@p, hope wargear and pts cost are at least in our favor. Hellfire rounds for the HB would be a good start.
