The pale yellow ground blends in very well with the pale yellow circle. I don't know what there is at the developers' disposal to address this, but perhaps a solid circle around the perimeter of the zone could help, or a tweaking of the mini-map's colour pallet?
Or maybe it really is just that people refuse to fight in the middle and they knowingly forego the objective in which case the zone could just be moved to the hills east of the middle.
