Looks good, and performs well.
There's a small glitch, though - in decay bone, the weapon remains visible, a bit elevated from the floor, until it vanishes suddenly (That looks especially bad with the hammer) - you'd better just have it disappear along with the body in decay flesh.
Another thing I'd mention is that you could arguably achieve that result using in-game textures, as Thrall's armor has that darker tone. But since you're going for very specific aspects in each raider, you may keep the custom one if you prefer.
Apart from that, it's good to go. All those raider variations could be very useful altogether. I'd recommend you had them all merged in a single bundle, even to have them better organized and accessible. (You may request it if you want)
Awaiting the fix mentioned above.
Approved
