I don’t know about other countries but as an Australian even on expanded I just don’t get into matches. Before the update that put Attack on Sanctum and Wasp into the game, I could stay in Balanced and stay in the lobby and just queue match after match. After the update I can only queue by going expanded and after every match of warzone I have to leave the lobby and requeue and it stayed like that for 2017 and 2018. If I stayed int he lobby it won’t match and it will tell me try a different playlist. And this is throughout different time periods of the days across an extended lifespan of Halo 5.
But this warzone turbo I am able to stay in queue and not leave the lobby which is incredible and I would appreciate it as an Australian to keep getting matches with playable ping.
