Actually, it would be quite difficult to remove that aspect of the game. Instead, I'd like to see HTC encourage some type of neutral battle ground between the bases. How or what I dont know.
But as long as players base their fun meter on how many bases they horde, there isnt anything we can do.
That atmosphere doesnt lend too much towards the "sim" feel of things, that is for sure. Take a look at a map of the Ost Front and there are vast wide open areas where there were no air bases. In the MA, they are within 25 miles of each other and the only thing to fight over are the fields themselves. I know HTC has to balance things out for game play, hence the 2X burn rate, close proximity of bases, etc, but it'd be nice to see something other than a horde over a base.
