It's me again.

This is another list I am considering collecting. It seems balanced, with lots of shooty units, which would be better at defending. However, with the inclusion of some
Sister Repentia in the army, I am unsure whether the Repentia should act as a counter in a defensive army, or the whole army should footslog forward, amassing a big charge.
Please give your comments, ideas, critique and advice.
Cheers!
