It’s on and off for me. Sometimes fast sometimes slow. For instance if I put down the controller during an unresponsive match for like 10 sec the game suddenly gets fast and responsive again. Or when I play a couple of squad battles before heading into a rivals game it has the same effect. Also in WL the games are unresponsive until like the last 3 or 4 games when you can’t get a higher rank. Not to be a foil hat here. But that feels like a pattern. Because if the game is slow and unresponsive it should affect both sides of the field.
