>>41066412think about it this way. the battle frontier is just a bunch of battle facilities in the same area. BW2 has multiple battle facilities that would make perfect frontier facilities, but scattered around unova rather than being in the same location. not the same thing obviously, but still, the world tournament is basically just the battle dome
plus the finals theme kicks ass
