More seriously, the problem is at least in part that people have different interests and reactions to elements of a game; some people want a lot of immersion, some are focused on tactics, and so on.
So while your experience may be '1-1-1-1 is fine enough, because I can think of the map in terms of rules and tactics and the immersive elements aren't enough to be a problem,' that's ultimately a somewhat personal reaction.
My primary interest in a map is looking down and seeing a rather transparent representation of what's going on. Having to bend my brain to conceive of the map in non-Euclidean space utterly defeats my primary interest in having a map in the first place.
Yes, it works. Yes, it's simple. Yes, it's fast. But it's not a map of the gameworld, it's a map of a tactical rulespace.
And that's tossing out something I'm vitally interested in.
