Helheim - lets burn some rubber

[Immaculate]

I tried to run a reverse communion with the thunderstrikes and blood sabbaths and it didn't work. If you'll bear with me, maybe you can explain what i did wrong.

i was breaking a seige from formoria (i hate formoria) and they had lots of troops of various sorts and i had about 12 helherdlings and some infantry and 8 vanjarls.

the first four vanjarls were scripted with:
sabbath slave, blessing, thunderstrike, thunderstrike, thunderstike
the next 3 were scripted with:
sabbath salve, thunderstrike, thunderstrike, thunderstike, thunderstrike
and the last was scripted with:
sabbath master, mistform, reinvigoration, air shield, reinvigoration


Instead they sat around casting holy avenger and sermon of courage and the sabbath master casted fanatacism.

Why didn't they cast as i was hoping they would? thanks for any help- i am still having lots of trouble with my sabbaths/communions.

Thanks ahead of time.
