I got in two games with my sisters last night using the Storm troopers and their Chimera in the list. It went okay each game, and I found I had a few rough edges from not having played using my Witch Hunters in over a year. I'll have to make sure I scrub up on declaring my Acts of Faith at the appropriate times, and also remembering to pop smoke at the end of a vehicle's movement.
After the two games last night, I've made some minor tweaks to the list. Dropping one of the Storm Troopers and the Chimera's Dozer blade lets me put the Mantle of Ophelia onto my Canoness. I thought she had it in my games last night and realised afterwards that she didn't. Things probably would have turned out quite differently for me if I'd played it correctly, so in go the changes. Anyhow, here's the new list:
Updated Army List
I'll be playing Wonna's IG tomorrow so we'll see how I go against a massed gun line.
