Since we're on the topic of Cersei's exit, can we talk a bit about why Dany never has Drogon fly her up to the Red Keep where Cersei is watching? The fact she chooses to burn the city and its inhabitants alive rather than using Drogon's fire to take out Cersei is absurd. Daenerys has mentioned over and over again that they need to work together to rip Cersei's hold on Westeros out by the roots. You can't tell me that she suddenly decided the evil queen wasn't the real threat, and that it was actually the innocent people living in the city who deserved her wrath instead. That's nonsensical, no matter how "mad" you think Dany is. She could've easily flown up there, had Drogon take a quick bite out of Qyburn and the Mountain, and then gotten some searing last words in before roasting Cersei like a marshmallow. That is the type of ending Cersei deserved.
