alright, here is my suggestions.
First off, I dont like the huskblade this edition. Sure, its nice and all, but being AP3 really hurts its viability against an all comers list. That being said this is easily fixed by taking a Power Axe. That way he would be able to cut through Termie armor consistantly. Also I am too questioning the Soultrap. Not saying it isnt good, but with the advent of the ability to deny challenges, I doubt your character will kill another Independent Character legitly to get the soul trap to go off.
Now the Haemie has a power axe, but why? He lack of an invul against things that will ID him (like what most ICs carry anyway) means he wont do much damage before a powerfist squashes him. Personally I would go for either an Agoniser or a Scissorhands (maybe a Venom Blade for a cheaper option)
Grots are fine
TB are fine
Wyches are intesting choice, guess they are there to haywire tanks dead?
ok, Im alittle confused on the warrior squads. Are the all 10 man squads??? Also if you are going for AT, then drop the splinter racks and run dark lance blaster. If you want AI, then run blaster, SC, Racks. If you are running 5 man squad, then drop the racks and just run the blaster. And no, sybarites are nevet needed imho.
Reavers are fine
Ravagers are fine
Personally I like to keep the darklances on the razorwing, but try out the dissies and see if they work better for you.
