Mainly the simplicity. If you want to hunt for fire type legendaries, you just joined the fire maps. Ghost types, same stories. Also, there doesn’t seem to be a ‘fly’ option or something like that. If I am at route 1, and want to go to route 20, I now have to walk the entire map to get there. I read somewhere the old maps were still available the first months after the new system got introduced. I honestly don’t understand why they got removed eventually. People could simply choose their own preference. I am an old player, idk, 2015? And wanted to spend some time here once again, but this new system honestly prevented me from doing so.
