What are your opinions about "Journey to Batuu"?

I bought Batuu singlehandedly for the BB and CAS items (I play historical gameplay and there are some great pieces for that). I got it on sale, and yes for me it has been worth it even if I've never, not once, touched the world or gameplay. 

I only got my first pet when it was free, and I do use some of the items. I've had a hamster in game once, but like with real hamsters, there is little real gameplay. I wouldn't have paid for it, but for free it was worth it.
