For the last 2 or 4 weeks the amount of lag I have been experiencing is unbelievable, every game I go into is unplayable. I must have lost 9 or 10 DoubleXP matches, It’s at a point where it takes about 10 minutes to bring up the pause menu to be able to leave.
Where are you from?
If you are not American you have to expect lag the majority of the time since the game heavily favours US hosts even if the majority of players are from another continent.
Partying up with friends from the same region may net you playable hosts more often.
Have you checked you NAT to see if it is open?
