Sorry, but I disagree. I think the little red and green arrows work the way the game should. None of this around the world in an instant.
I get what you are trying to accomplish, but the map creators are able to channel fights in a number of ways. It is the territory grab that replaces that. So, basically no one really knows how the terrain will play until it has been in rotation a few hundred times.
To give an example of the kind of players we are working with, a common practice in wee hours and low numbers is for bombers to get up high and fly around unmolested from one end of the map to the next. Unless you are the bomber, very boring and not what I pay 15 bucks a month to play online for.
If I didn't want anyone to engage me, I would just download the game and play offline. Just my two cents (probably two cents more than needed).

And yes, the Main Arena could benefit from the skewed map even without the limited planeset. What the addition of the global map in the AvA does however, is ADD areas where a broader crossection of planes could be played with a single terrain.
