I actually cant afford more venom warriors squads, because of lack of venoms, got only 2 at themoment. I find FF very usefull all the time, i dont even know how many times it saved my machines from exploding and killing full squad. Blasters on the warriors squads are for the additional threat for enemy from them, and that one more darklight shoot if I had to open some pesky terminators. Becouse of not having second ravager at the moment, and if i get some points at cutting down the point cost of few units, is it worth taking reavers with heat lance/blaster, for additional high str low ap shot, or with cluster caltrops for better bladenaving, or they are not worth at all??
