I’m from the UK and regularly play with a friend from the US (east coast). In OW1 and for the first few months in OW2, it seemed random whether we’d be placed on a UK/EU server or an east coast US one, which I was fine with.
In the last few weeks, when we play we are always placed on a UK/EU server, so my ping is always OK (30-40 ms), and my friend’s ping always sucks (120-140 ms).
This happens no matter what game mode we play.
Has anyone else in a similar situation - playing with people where there’s a fairly big time zone difference - noticed the same thing?
