I can't seem to find any Rush servers for about a week, I have played the game since 31 December 2019.
Even worse is that when I log in, 50% of the time when I'm server browsing, I can't see any Non-premium servers
When I finally can see Non-premium server, I usually only see 1-2 and those are either Operation or Conquest.
I have tried quickplay 2 times, to find a rush match. First time the matchmaking system couldn't find me anything, second time it putted me in a match with 1 other player on the other team and said "beginning when there is enough players" Which in this case was 5 on each team.
