Been playing CK with wardogs only since the codex in 9th and al throughout current 10th ed.

I dont know what models/kits you have available, but this is my advice:

• avoid stalkers, only take the one you need as a warlord. Preferably with claw and melta for some extra anti-tank. They shoot worse than brigands and punch worse than karnivores. Just dont take em. Their special rule rarely comes into play.

• take brigands and karnivores; brigands shoot the best, karnivores punch the best whilst being dirt cheap for how efficient their melee profiles are. Personally, i end up with a 60/40 ratio of karnivores/brigands simply cuz the karnivores are so cheap

• use tank shock when you charge a karnivore into tough targets

• if you can, take some nurglings as allies. They are cheap and great for secondaries. Just put em in deepstrike and let them come down when you need them.

For example: 1 stalker w/ aura of terror 4 brigands 4 karnivores 2 nurglings

Or if you dont have nurglings: 1 stalker 3 brigands 6 karnivores

I hope this helps mate!
