Personally speaking, those living in the US shouldn't complain. Because they are closest to the servers. When they really do complain, they should feel the other players' agony (not living in US but in other countries) that their lag is 10-100 times more. LOL.

So if the players' rage in the US about lagging means you are hammering your phones or laptops in frustrations, then other players in other countries most likely are taking out their chainsaws trying to saw their computer or phone into half..lol...
