If you've got decent internet, use a wired connection, have forwarded all ports and have little network traffic, there is nothing more you can do. EA support will continue to claim their servers are exceptional and their matchmaking and games are designed by geniuses so the problem is your end.

Read through this forum and see how many people experience unplayable lag constantly but EA don't even bother to respond. The sad fact is you could have a console/pc with solid gold wiring, a fibre optic connection direct to EA's servers but you'll still experience MASSIVE lag due to EA's crap servers, matchmaking that a child could better, and the huge input lag in this game.
