Not sure if previous updates were like this, but this one requires a lot more hand waving than usual to explain. But it's still fun to theorize. At least the lore isn't in the way of cool updates
I mean I guess there's just no consideration for lore in dota updates. From what I saw, Valve kept the art style so it kinda fits in, but it doesn't seem like there was any consideration for anything to fit into the lore. So I feel like he did this video with absolutely nothing to go on, so it makes a lot of sense that there's lots of handwaving.
