Disappointing Game Freak once again turns to Japanese only exclusives. It’d be nice to have a fair distribution to all players to share in events when they’re released. Other companies like Capcom have become smarter on this with games like MHW over the years. Region exclusives only disappoint the fans and even support the hacked pokemon to happen more.
