Absurd visibility problems in maps

Because of the perspective, you pretty much can't see that there's a cliff there. Definitely doesn't distinguish itself enough from the random rocks.
Maybe it's partly due to shadows? Looking at it, and walking around, it's hard to even tell if it's going up or down, or is just a random "wall".

It's really not ideal having to play with the minimap open to this extent. Especially when the minimap can be intrusive to some, and the defaults are shit.

In addition, the 'fungal' type maps have a similar issue.
Theres a wall/terrain and it isnt abundantly obvious that theres a wall there other than you cant walk there or something has blocked your ranged attacks.

POE1 belly of the beast maps in Act4 & 9 did the same thing.
