This is most likely the case at the moment. Though if their servers weren't hosted about as far away from all major centers as possible it would help.
Meh, the gameplay is chunking, one of the pipes between me and the servers is pretty full a lot of the time, feels like they've added the bare minimum of capacity at the servers. The same way Coil gets full on Tuesdays on Tonberry, we're going to get chunky performance in other areas simply due to being a higher population world. Unfortunately this seems like the status quo for Tonberry.
