Do you use quick match or server browser?
Quick match seems to have a habit of putting you on servers all over the world.
I've ended up on US ones before and you get shot at before you've even seen the other person coming.
In 1v1, time after time they are shooting you first. Its like your reactions have turned into that of a 70 year old man.
Change servers back to a Europe one, and its night and day different.
Yeah I was aware of the quick match issues so I tried a few european servers through the server list but the same thing happening, I'm going to go play with some router settings I shouldn't really need to but don't have much choice at the min. =(
