If you guys are in the UK I suggest you set up a Broadband Quality monitor (it is free) with http://www.thinkbroadband.com
It's easy as pie to set one up and it pings your connection and builds a graph that you can view.
I am not saying this because I am blaming anyone's connection, but these monitors are good for general and understanding your internet connection better.
I am aware that people mention this issue with gameplay and to be honest these conversations go back years and years.
What time of day do you mostly play? Have you played beyond 11pm UK time and noticed different gameplay?
The issue is that not every player has this issue. I know the issue exists but the reasoning behind it is complex. If it was every single player no matter where in the world then of course EA could focus solely on resolving that. But, when x amount of people mention having it while others are clearly either one not experiencing it or don't notice it and playing on.
Again in regards to that monitoring tool. They are good to have anyway.
And to the chap that has Virgin Media. What does a ping test to the likes of 8.8.8.8 return you?
