I just play Durge. Can’t play Tav anymore due to loss of content. Like you said, it feels empty. I suppose the player needs to think of a backstory and interject that for themselves. A valid way to play. But I definitely enjoy Durge more. Good Durge’s ending, for me, was super underwhelming though, which doesn’t make me feel excited to play through it again. I would say that it’s the most underwhelming thing about act 3, to me.
