Yeah, I think they messed up with allowing 200 friends. Who the hell wants to juggle that many people? I would have preferred, say, 20 local friends and 3 international friends that can be traded with, even if there's an international stardust penalty
I'm glad the system is there though. I'm more interested in how they can use it to improve raid organization and simple communication. The potential is there if Niantic is wise enough to use it
