Snowy Escape EP - What are you most disappointed about?

I'm disappointed with the apparent lack of integration with the overall game with basically all the new gameplay being contained to the new world, it just seems like if you're playing in any world other than Mount Komorebi you might forget you even have it installed. This makes it feel like more of a game pack to me. I had the same complaint about Island Living. Now granted I haven't bought the game yet so this is purely based on what I've observed from trailers and overviews on youtube
