Well, the high ping is consequence of both overpopulated servers and the distance to NA (with a bonus to bad routing). Sure in non-peak times its considerably better, but it’s still much worse than playing in a local server. There’s no comparison between 10-50ms one gets to a local server, to 140-200ms the same player gets to NA.
If they solve the overpopulated servers, we will still have a significantly disadvantage for any PvP mode, not to mention the lower time to react boss moves and the instable routes we get.
