I think this is the issue here, Edelgard is set up to be questioned. If you play her route, it only gives out information that would make a player support her. But when you play the other routes and you start seeing a more complete picture of the setting. All of this information pokes many, many holes in her reasoning. If we were to see more of the nobility, we might see that they actually had more complex reasons to do what they did.So, does anyone else think that they could have shown more of the Adrestian nobility? Because for all of Edgeguard's talk, the only ones who's actually shown was Ferdinand's father and her scheming uncle while everyone else was mentioned in the students' support conversations.
At least with some of the older games, we get a shot or two of who's plotting against you.
After all, the coup against Edelgard's father was supposedly because he was centralizing power.
