I did some testing and played some pro clubs game after the 1.5.4 update. The game is kinda better now but only if the total players is low in the match (around 9 players max). If there are more players it becomes very delay. This is already common and people know about this already, but the thing that saves us a lot of frustration is that when the game fast forward itself to sync the with the server for that match.
What i meant by "game fast forword" is the players and in game match timer moves very fast to keep up with the server. This feature is a life changer for people who has low PC specs and unstable internet connection. Even if you delay a bit maybe by graphic issue like freeze for 1 second or maybe by a slight ping jump, that "fast forward" to sync the server could help out. Usually before the 7th april update, the game fast forword after the ball is out, offside, a goal, or keeper catching the ball, etc. Now it only fast forword in half time which is bad. Please add this back as it can help out some people with low end PC out there or unstable connection.
