Thanks Magister187.
I played a couple games last night and the night shields did ok.
I changed my list though and am going to try out a build with some of your suggestions in mind.
Here's what I have:
5 Warriors 1w/blaster
-Venom w/extra cannon
8 Wyches 1 Hekatrix w/agoniser
-Raider w/dark lance
1 Ravager w/1 lance and 2 disintegrators
So I dropped all the defensive vehicle wargear, venom blade, and the hydra gauntlets for a blaster in the warrior squad and an agoniser for the Hekatrix.
I agree with having 3 dark lances on the Ravager but at the 400 pt level there aren't a lot of high armor values and if I target infantry I'm still dishing out 7 shots.
Thanks for the feedback and if anyone has any suggestions I'd be thankful to hear them.
