I do agree that it would be nice if the threats of the main cast felt more substantial. Given the risks that they keep bringing up, the ending of ShadowBringers would definitely be a good place to actually remove some of the cast for good. Or at least lock them to the Source so that they can't come back. Fake out deaths are fine in small number but once it sort of becomes the expected then it feels like more of a joke and even when a character really does die you just end up rolling your eyes and wondering when they'll come back.
