I'm just confused as to why they have restricted EX Raids to parks and sponsored gyms. I never have occasion to raid at either, so I guess I'll never get a pass. ¯\_(ツ)_/¯
Why? If you want to fight Mewtwo, this is how it's going to be. There should be several Park Gyms in your town/city.
The system still has major problems, but it seems that even more parks are opening up. The EX Pass that I just got was from a different park than my previous one.
At this rate, it seems that active players who haven't received an EX pass yet will inevitably be getting one during the next few weeks.
