for one thousand points I am considering
1 sorcerer (terminator armour, personal icon, wind of chaos)
5 terminators (1 champion, icon, chainfist and reaper autocanon)
10 chaos space marines (champion (with plasma pistol and power fist), icon, autocanon, melta gun, melta bombs)
10 berzerkers (champion (with power fist, melta bombs and plasma pistol), 2 more plasma pistols and icon)*
Predator with twin lascanons, lascanon sponsons, havoc launcher, extra armour and dozer blade
*i made the berzekers kind of like raptors without jump packs by removing all the khorne insignia and giving some of them parts from normal chaos space marines as well as using normal chaos space marine heads.
You really need rhinos for your troops!
Also, what is the overall plan, what will the termies do? Deep strike? Walk?
I'm guessing the sorcerer will be with them, he only has one short ranged spell, give him a mark at least. Combi-weapons are good on the termies, see if you can fit some in there(combi-melta being the top choice).
On your aspiring champ it's better to have a combi-weapon instead of the plasma pistol. it's cheaper and he doesn't have to give up anything. He will most likely only get one shot with it anyway. (if something is within 12" it will either assault you soon or you will assault it soon) A CSM squad is more often than not good off with having two special weapons instead of spec+heavy weapon, get them in a rhino, get them close and unleash the fury of the chaos gods! Hehe...
When the zerkers are in a rhino(which they need to be), bring them down to 8 guys. Not only is it fluffy, but they will fit around one hatch when disembarking, and most likely won't "overkill" an enemy squad, leaving them out in the open to be shot at the next turn...also, meltabombs are kinda bad. You get nice penetration, sure, but against vehicles your fist has more attacks and will hit the rear armour anyway(10) which is better, and against walkers you'll need a 6 to hit with it. Better to just melta it with ranged!
The predator is a bit too expensive. Since it has to fire all things on the same target the havoc launcher doesn't really go well with lascannons. The extra armour and dozer blade are also not that good actually. I've yet to see my pred immobilized by terrain or just getting stunned. For me it usually either survives or is viciously destroyed in cc or with melta at close range...
Also, welcome to the forum! :)
[Edit]: Also, looking forward to see pictures of those berzerker conversions, sounds like a cool concept!
If the sorceror is hanging out with the Termies, then you don't need the personal icon; only the termies can deep strike, so it will be wasted.
And welcome to the forum : Thumb :
