Revelations from Patch 3.56

[Theodric]

Agreed - if there was anything that could be described as being enforced it's peace between Dragon and Man. At no point do we try and change the system of government, instead focusing on bringing to light the truth behind the conflict.

The shift in government is on the shoulders of those like Aymeric.

The Warrior of Light - and certain Scions - frequently met with Aymeric and other influential Ishgardians during their time operating out of the city itself. It wasn't wrong to go after the Archbishop and his supporters but to pretend as if it wasn't done - at least in part - to bring forth change is simply false. Even after the Archbishop ceased to be the Warrior of Light actively aided Aymeric in assaulting those who remained loyal to his father's cause. If that isn't classified as actively meddling in political matters and ushering in a new government then I don't know what to say.

Aymeric played a part, certainly, but he leaned upon the Scions and Warrior of Light to ensure his success.

Pretty much this.

The same goes with Igeyorhm. The lore book had some neat background on her, on how she is ashamed and seeks redemption by working even harder for her cause - yet in-game she lacks any such presentation. Depth to both sides is something I appreciate in storytelling, not necessarily "grit" and "edginess."
I think it's fair to want both sides to be equally represented, with our side not always being the squeaky clean victor (which 3.4 and the WoD did a lovely job of and I hope to see more of in the future).

Yep. It would have been very interesting to see her past revealed, perhaps through some sort of vision using the Echo. It's a pretty major plot point for her to be responsible for the creation of the Void but most players are unlikely to ever know about it unless they study the lore book intently. Hopefully Stormblood gives us many more scenes with the antagonists to better explain their motivations, thoughts and feelings. When I think back to my favourite Final Fantasy titles - VII, IX and XII - that was something that was very common and ended up being effective.
