For months I thought 343 would eventually solve the issue. But alas, here we are, 6 months later and Halo 5 has been reduced into one mode in Australia: Warzone. It is the only playlist that Au players can find a game in within 3 minutes. Sometimes if you are lucky, you can get a Team Arena game, Grifball or Social game.
Halo 5 in Australia is becoming a popular game. We may only have 23 million people on this island, but we still deserve your amazing game.
