I just finished the new content and it's really amazing. I ran an INT build, with a freezing staff and a curved sword to smash the frozen target, and I loved how broken it felt.

The new areas are great and enemies are great (just defeated the hiddedn egg head boss)[/spoiler, so are the QoL improvements (and thank fuck for finally having some basic waypoints travel).

I also liked how much some of the areas changed based on the story, it really feels like a world instead of a map to grind on.
I have no issues with the game anymore and all I want is more content and a story tying it all together.

It feels like they have about 50-75% of the world map in place.
My only worry is that it will take 2 more years to wrap it up, including adding MP (I'm not sure if it's just coop or they want pvp as well) which I don't really care for.
