Provide sub-regions for US region, perhaps useast.airvpn.org, uscentral.airvpn.org, and uspacific.airvpn.org? This will minimize latency on games that try to connect you to the closest server by having your exit ip to be in the same area.
Manually managing the different local region servers is a pain when some are offline while others have high packet loss. It would be nice to be connected to the best performing local region server and not the one across the country.
