Right, guessing the doom blade is a special character Killer or something?
Either way you can alway say that "X does to Y", the wood elf thing may die straight up to my butchers cast of the maw, or a chariot to the ace, or something.
And comparing the models is also totally obsolete, he's not a wood elf. Just like it'd be silly to compare him to a Saurus.
He's a nice chaos marauder model, and he does what he does. And he's not indestructible.
