It's refreshing to see other people have the same or similar take on Dynamis that I do. As soon as Nidhana mentioned Akasa and what it was, I started to get concerned. I said to myself, "I really hope they're not introducing a major element to the story this late in the game that will end up feeling like something they pulled out of their rear ends." And I was right. We have this brand new lore element that is driven by emotion, so one can conclude the power of friendship will save the day. Dynamis, in my opinion, made things far less threatening and more predictable. At no point in the story did I feel as though things could go south. In Shadowbringers when the WoL started to turn into a sin eater and the light was consuming the First, there was a sense of dread and it left me wondering how the WoL was going to get out of the situation. There was none of that in Endwalker once Dynamis was introduced.

Also, you mean to tell me that none of the Scions knew about Akasa? The Scions who studied in Sharlayan; The receptacle of the world's knowledge. Neither Urianger, Y'shtola, G'raha, or Krile ever discovered texts on this and knowledge of Dynamis was ONLY in Thavnair? I know people will disagree, but that's too farfetched for me to believe.
