My main problem with "world navigation" (aside for, guess what? Once again the horrible the party controls) is that the camera is borrowing from DOS 2 the same bad tendency to "deform" things a lot.
You can notice it clearly when you have two creatures of the same size (i.e. two goblins) and they can look even four or five times bigger/smaller than the other according to how close/far from the camera they are.
A more "orthogonal" camera would prevent things from being so hard to keep in view and maintain coherent proportions. It would also prevent more elevated environmental details from "shooting" directly into your eyes covering view when rotating said camera around.
Just saying it for the sake of it, to be honest. I have very little confidence about Larian ever addressing this.
P.S. If this attempt to an explanation sounds particularly messy is just because a language barrier is preventing me from using the correct technical terminology for what I mean in English.
I apologize, but please make an effort to grasp the general sense of what I'm trying to express.
