On Gaius
While I like Gaius as a character, the WoL's continued dislike and mistrust of him is completely justified. I feel that if SE was going to take the easy way out with Gaius they wouldn't have shown that continuing distrust. Nero also started out as an enemy and is now an ally, and we didn't instantly trust him either.
In 1.0 Gaius was presented as at least being capable of reason and restraint, and served as a foil for Nael. I don't really feel that that "misguided but not evil" is a retcon of Gauis's character in 1.0 and ARR rather that we are learning more about the character (and the Empire) than what we knew before. Characterizing them as misguided doesn't justify what the Gauis (or the Empire) has done which is something that Gaius himself seems very aware of. I think that evil actions can be done by people who aren't inherently evil or for reasons that aren't or at least don't begin as inherently evil is one of the big themes of Shadowbringers as a whole.
I was skeptical of Yotsuyu's patch arc in Stormblood when it began but ended up liking it. The writing overall has been excellent in Shadowbringers (although I think the Eden story in 5.2 was a weak point) so I have hope that whatever arc they have planned for Gaius will make sense within the FFXIV world and plot and not just be shoehorned in because he is a popular character.
