I agree Hades in the sense that I try not to be spoiled by watching anymore than I have to, but I do my best to watch all of the videos they release outside of streams, since I love hearing about the new information when it comes to races. That said if this is really the case, then that's a bit disappointing. It does take a lot away from the other races in the sense that their race-specific abilities are shared, making them even less useful in a party of mixed undead and living.
I do hope they rethink this, and that these video only showcase an early build of how this mechanic works. Aside from that though, I enjoy everything else I've heard about the undead race.
