Haemonculus ideally starts with reavers then jumps into the trueborn venom. (where else could he go?)  Farseer goes with reavers or hangs back to guide war walkers and ravager.

So I tried making the best list I could with what models I have. I would like to have 2 more ravagers or a Razorwing but I don't have the models.

My questions
1-I am worried about my opponent getting slay the warlord, any ideas to prevent this?
2-Are the war walkers enough AA?
3-(biggest question) 5 wyches w/ HWG or 5 warriors with blaster for my 2 venom squads?

Well you could equip the warwalkers with missile launcher and sky fire them. They are great at taking out air. As for the haemonculous I would make it an ancient if you could and put him in the trueborn. But the list is interesting you have to let us know how it goes!
