Just gonna ask a question
If your psn is EU or your version of the game is... You only play with the people in there? or universal? Just making sure though or your internet connection is the reason why you can't get good matchmaking?
Im just losing patience on the matchmaking <.<... But still Crysis>CoD.

I only play against people from the EU + a lot are from my country. But people here don't believe me. *-)

EU Psn and EU game here and i mostly get put in games with europeans (atleast i think they are) and a lot are from my own country.

I would assume that matchmaking prioritizes those in EU before expanding to other areas, as the closer you are to other players in the world (in terms of location) the better the connection will be.
