Sorrow of Werlyt
I'll admit my first reaction to Gaius becoming the new commander of the Werlyt rebellion was "Really?" But I digress. The fight with diamond weapon in normal mode was fun, and the change from Zenos to Alfonse as the "Data type" was quite interesting. Props to those who bet on Diamond not actuallybeing Zenos. Valens showed himself to be as disturbing as ever, and quite good at combat provided he knows his opponents moves before hand. Regardless, I am glad Diamond Alfonse managed to quite literally pop him before he deactivated. I'm still 50:50 on Gaius being an advisor for Werlyt's independence but at least he got out of this with one kid.
EDIT:

I have to say this was underwhelming, even w/o the hype of being a Nier/Yoko Taro advocate. Everything being resolved with "portal from another world" is fine and dandy, but taking away the framework of the "Taroverse" and what are we left with? In my opinion, a very unengaging story that I couldn't connect to or recognise the themes of. I'm still going to do the weekly quests, because apparently we are going to get memos from here on out that might actually explain what the heck happened, but I'm not holding out hope.

Damielliot lives again, AND he speaks! Glad to see Tiamat freed and moving on. Meracydia seems to be off the table for 6.0 while she tries to reign in and comfort what remains of her Horde. Maybe for the next expansion. I was expecting Arenvald to outright die, and now I'm even more dubious about them going all the way on actually killing someone for narrative stakes. Krile acting as the Eorzean emissary to Sharlayan was an unexpected outcome, and while I am certain that Hydaelyn isn't as maicious as other primals and just didnt know how to go about things the right way, I am glad that the Scions have gotten around to asking questions about her and the Blessing of Light.
