The population in the USA is 15X Australia. Therefore I don't see any solution for your country. You could try to find a VPN to China that Battle.net doesn't block, but both China and Russia by far have the highest concentration of hackers. Otherwise India, Thailand or South Korea. I would imagine the pings would be unplayable to the USA.
This is yet another problem with this matchmaking p2p system...BRING BACK RENTABLE DEDICATED SERVERS!!!! Oh I forgot....they want the micro transactions the greedy bitches.
Tough to find a loby in Blackout these days. Generally I can only get one if I play the "hot prusit" mode. They should make it cross-platform! It suks when my favorite game is dead.
In the USA, Canada and North America Blackout certainly isn't dead. This Forum should make it mandatory to show where people are located.
