I think it's kinda because when an empire threatens to take over your homeland and a giant dragon blows it up you realize there are things more important than money and booze and should maybe probably work for the greater good.

I feel the same way about Ul'dah and the Pugilist's Guild. The guild used to be a training center for people working as hired muscle for the Platinum Mirage (the casino/bank right next door). If anyone owed money to the Mirage, they'd send some members of the guild to beat the hell out of them and collect their money. Now what is it? They do nothing but box all day with no point or place in society. Why was everything in Eorzea cleaned up into sunshine and rainbow land for ARR?
Are you serious? There is innuendo all over the place and there are hookers in a ton of Ul'dah cutscenes.
