I really like how the later ARR+HW stories are getting into political discourse and conspiracy. I love those kinds of stories and it leaves me hungry for more.

It's also the little things that do it for me. The way those Vanu Vanu dance with might, getting minions from beating a Fate boss, and those one-off, silly quests/side stories that make me smile. While it has its flaws, it also had a lot of heart put into it, imo.
