Actually list looks very solid, maybe Id swap blessed weapon for a master-crafted eviscerator if you concern self with heavy melee troops.

Maybe equip the first squad with heavy and regular flamer. They do add about 3-6 hits each on average. And beef up both squads with any points left, they will need extra bodies to march closer to their destination.

Thanks for the feedback. I have redone the list using your advice and I hope it looks a lot better. I am not really concerned about heavy infantry as my exorcist and the meltaguns should be able to give anything a good pummelling before my canoness flies over to finish them off. Just in case though, I have given the canoness an inferno pistol so that I dont waste her high ballistic skill.
