Landscapes I would like to see in future.

[Atoli]

a dense, darker forest with tiny narrow paths, mazelike, where you have to push through the leaves and undergrowth.

I am not talking houses on stilts like the ones with the sylph - actual tree houses with rope pathways ect.

1.0 Shroud was mazelike and everyone took forever to get anywhere and players complained how, while it might be a nice design idea, it fails on an actual gameplay level.

In ARR, they actually had to add a railing to the tiny ramp leading up to the Sylph house simply because one of the most common complaints they got was that players fell off all the time trying to climb it.
Excuse me, but I think you are vastly overestimating the general Player's ability to navigate their character xD

The dev team played it safe, yes, and I too wish that some areas had a bit more visual oomph, but they played it safe because it was necessary.
