Since last week I have only been able to find games in Warzone, with all other playlist failing to find anybody else. This seems to happen regardless of time of day or day of week, and still applies when players are in my party, although it is fixed when another player is party leader. For group play it’s a non-issue, but individually it’s essentially preventing me from playing any arena, and Warzone assault.
Maybe it’s because people in your area/state/country only play WZ. I don’t know what else the problem could be.
Its -Yoink-, all my friends have this issue.
Where are you located? I’m in Australia and we’ve been having problems like this for quite some time. We’re down to Warzone, Team Arena and sometimes Slayer.
