Funnily enough Eureka, & Bozja faced much the same issues where people were rather dissatisfied with them in the beginning. Eureka especially, but even Bozja was mixed.
I was not expecting anything to be any different in the new zones and I have not even gone there cause I knew the devs would screw it up, cause they always do when they add something "new".

Island Sanctuary was mediocre, V&C was a mixed bag. The only thing that works to relative success is Deep Dungeons, but thats due to how incredibly formulaic it is so it would be incredibly difficult to mess it up.
But that also has the downside where things become TOO formulaic and people have started to notice a trend there as well. Dongeons are ok, but formulaic etc.

Players are both fed up with formulaic content, but also when they make something less formulaic it always has some major issues.
And here's the kicker, it takes TOO LONG to fix. Forked Tower would probably have been better received IF the devs just applied a hotfix to it within a week of it's release.

But no, they're so set on their ways of formulaic update cycles that they can't provide a hotfix unless it's RMT related.
