I live in Belguim and it is a bit laggy that can't be helped but tbh it is fine here. I mean, sure it is not as smooth as League Of Legends of exemple but it works pretty well .
And are you sure it is not from your own computer ? i mean that your ping is fine but you have a Low fps. Because My lag is way bigger in a PVP fight than when I walk around the world map, try maybe lower settings to see if that helps ?
