From what we have seen so far, killed enemies will disintegrate without any blood effects. This really bothers because it looks so unreal and stupid. I don't want the game anywhere near as gory as Gears of War, but I want some realistic blood effects and ragdoll to balance out all the space magic.

I don't think the game needs gore, or to be realistic. Also the enemies only disintegrate when you kill them with magic.
