Ok, I liked your army, for friendly play.
What I dont like is that all your eggs are in one juice bag (AKA BCs in the LRC).
I would only change 2 things, get rid of the Dread with Lascannon and the predator.
With the points, get some Scouts kitted for tank hunting and OBEL them.
And get Drop Pods to your Dreads, they can unleash some mayhem in your enemy zone when they arrive, thrust me.
Oh, and if you have the points, give your rune priest some Inv. Save.
Otherwise, have fun, the army is nice.
See ya.
