I find it strange that they weren't more specific about that point were it truly the case pre-Sundering; moreso because it would've more strongly pushed Venat's group as being right when the story already leans in that direction to begin with.

It's all the vagueness surrounding basically everything that happens between the end of Elpis and the Sundering the that makes it hard for me to feel completely for/against either faction's course of action, though perhaps that was precisely the writer's intent.
