HQ:
1 XV8 commander crisis suit with 2x burst cannon, drone controller, and 2 marker drones
i like burst cannons on cammanders, 8 shots at
BS 5 and is a cheaper option is never a bad thing. target lock IS a must though. i know many do, but a would not put plasma or fusion on the commander. such weapons tend to encourage you get close to the enemy to benefit from rapid fire or melta range. your commander should not be trying to do that.
Elites:
3 XV8 crisis battlesuit squad with 2x missile pods each
solid choice, considering running them as 3 indiviual suits
Troops:
11 Kroot Carnivores with sniper rounds
9 fire warrior strike team
10 fire warrior strike team (with shas'ui)
i personally would not run kroot at all, and if you are, spending more points on them is a no no for me.
run the firw warriors as 4 units of 5. more objective holder this way, same fire power at more targets. also fire warriors will die in combat whether its 5 or 10. i would go for versitility here.
Fast attack:
10 Pathfinder team
2 units of 5 is my suggestion if you want to use them. my advice would be swap at least half for a marker drone unit that can join the commander for BS5 markerlights
Heavy Support:
1 XV88 Broadside Battlesuit with twin linked heavy rail rifle and twin linked smart missile system
Agree with the other,
HYMP over rail everytime. though considering the rest oif the list, the rail has a place in your list
Hope this helps.
if you want a fun list, look at some of the suggestions made.
If you wnat filth and either have models or are willing to spend. say so and i will give you some ideas.
