My theory (based on Kabals) was to have Dissies mounted on Ravagers, then splinter loaded onto Venoms. With Coven, I dont have access to Dissies without Raiders, which leaves splinter on the Talos (need splinter in the army, so wont be changing out to a different ranged weapon).
But with Dark Cornucopia to assist with movement, I am thinking that Coven should probably be a Foot force instead of the usual DE Mechanized list. But then I would be completely dependent on a very expensive Stratagem, which can only be used 1/phase and can only move 1 unit.
Which brings me full circle to: How do you design a Coven battalion? Do I completely do away with the transports and invest in big blobs of Wracks and Taloi (who Fly and cannot be tar-pitted), do I drop the Battalion and go back to my usual Vanguard/Spearhead of Grots/Taloi (and loose out on those sweet CP), or do I stay with the Kabal template of Mechanized (but without the Kabal firepower).
Edit: Just remembered that you can Fire and Fade the Wracks, but only if they have a ranged weapon. That would give the Foot army a little more mobility (but place additional burdens on my valuable CP)
