Okay, I finished Act V and...
SOME OF YOU PEOPLE CALLING THAT ARCHON QUEST TRASH!?
Bro, what are some people smoking that they oppose the story of Natlan so bad? It was high staked, quite focused and tied most, if all loose ends. All the callbacks to previous acts and to characters from both the AQs and WQs was a great call: even Nepecha, Nechca and my little buddy GOJI was there! It's not perfect, but it's great for Genshin standards.
I'm gonna say it... 2nd best AQ. Not kidding. It's Fontaine, then Natlan and then Sumeru, no contest.
