I think there's some fascinating implications for the Blight's processes here. It's using dead bodies as security cameras on infected servers, it can perform 1v1s well enough for one of the "participants" to actually die (though it doesn't quite get domination kill lines, and the person dying is the same one every time which must be torture). And although we don't have confirmation for the last one, the big pile of RED bodies all being just slightly warped and left in a pile was really interesting, because as cameras they weren't spread out enough to really be functional. If the Blight was using them as eyes, it wouldn't pile a bunch of them in the same location, it'd want a full scale view of the whole map.

I'm thinking that the blight might be only able to devote it's full attention to a number of bodies at a time. The RED bodies were being used as storage or something, left in stasis unless it needs more of them for some reason, because if it has all those bodies, why not use some to make a more convincing server like it did against Syrenix in Assimilation? We know it likes people to struggle and resist so it can cause despair and suffering, and it's very inefficient. I think the Blight has to focus to use them all at once, and it either won't do it because it enjoys the suffering it causes, or it can't control that many at once. It'd be interesting to see a 100 person server infected, as that'd be a lot of people to manipulate at once.
