Same goes for Battle Frontier, though I wouldn't exactly call it useless, it's definitely a feature that does not *need* to be in a modern Pokemon game. With the advent of competitive online play, I firmly believe that all any game needs is something like the Battle Agency and the Battle Tree. As far as the Battle Frontier goes, yes, even I want it back, but it's a mindset that you need to get into. The reality is that it's simply never going to happen with GameFreak's new design philosophies.
