What pack content or gameplay surprised you, good or bad?

When I finally got Batuu, I knew what I was in for and it was that bad BUT I was pleasantly surprised by the droids. I feel like they're what familiars should have been in Realm of Magic. Of course, there's that issue of them not being functional outside of that one world, so. Last bad surprise was NAPs. I really thought they'd help give a little life to neighborhoods.
