What threw a lot of people was “Complete the following Kul Tiras and Zandalar acheivements,” but it looks like it is just the exploration achieves for Zandalar.
Overall, I like the expansion also, but how that ship is placed is tough to find and get on to. I like the Alliance city, but yeah, the city is tough to get around.
I ended up going Alliance this expac because I like the Jaina story and I am not thrilled with Trolls in Warcraft. I will level a horde toon to see the story, though.
