I'll have to think about this one a bit. As Sandman suggested, it would definitely be a big lift. That doesn't make it a bad idea, just an expensive one... and at this point in Demon's development there are still lots of other cheaper ideas that would probably have a bigger impact.
But, on the other hand, what might be more doable before then is trying to get demons to formation themselves at least a little better? I'll put investigating that on the "soon" list: I don't have an ETA for it, so I don't wanna tie to it a specific build just yet.
Thanks for the suggestion.
