You started this thread and it was obviously about your want and desire in spite of your use of 'we' and Google.
So instead of flying hundreds of miles and taking an hour to get across the map, you just up from a base on your edge, then fly off the map and magically appear on the other side of the map instead? Yeah, that's not gamey...
If the maps were designed with that in mind it wouldn't be. On the current maps it would be.
You can already do this, you just have to fly 8 sectors to do it. Its VERY effective for supprise bomber raids, since the enemy doesn't expect you to appear behind their strats.
Lol, I did it once, ended up too far south of my target, and then actually did trig to find the exact angle I need.
