Didn't Arkhona just re-emerge from a warp storm or something? I thought that was the lore reason given for it being barren and lifeless but still covered in functioning Imperial equipment
Who even cares about the world "map"? (apparently people in this thread. Dumb question.) You can barely even call it a map. You can simplify it down to some tug-of-war google-docs bar graph for easier readability, I don't care though. It's just lazy eye candy for the <1% of game time you see it. I would like to see some interaction though. Like choosing which front to fight on, certain territories giving unique bonuses, faction specific map bonuses like eldar being able to attack any location (just an example), 3 sided battles (ork v eldar v sms), or tyranids screwing around or something. Who cares what the map LOOKS like. Lets give it some function.
