Playing with a close friend and we feel like these two important features are missing.
Linked players should change channel together so they don't lose each other constantly when the servers are crowded. maybe there could even be an option to join a private channel so you could journey with only your friends and not the crazy cosplayers with legendary pokemon.
Also they should see each other on the town map also for finding each other and getting the feeling of playing together in the same world even when a little apart.
