Ok, no one is going to believe me, but I HAVE to say something.
At my home, we have a DSL connection. My husband works from home, and wanted to make sure that we had redundancy in case anything happened. Also, he loves me and wanted to make sure I could not only play ffxiv while he's working, but that I could also watch Netflix. Yeah, I'm spoiled. But that's beside the point.
We recently added a second internet connection, this one is cable.
So, we have one DSL connection and one cable connection.
We live in the US and play on a Japanese server.
We have both noticed lag spikes and weird latency issues when we are playing via the cable connection.
We have also both noticed that we do NOT have these problems when we play using the DSL connection.
I notice lag spikes while CRAFTING. I'll hit an action, and it takes 4-5 seconds for it to actually happen. And/or the action happens, and it takes 4-5 seconds for it to stop 'thinking' and allow me to select the next action.
Also, while watching mythbusters recently, they timed the speed of a bullet. I can't remember the exact number anymore, but I had to stop the show, go back and listen to it again. The ping time most of the people here are expecting to have, is faster than the speed of a bullet from a sniper rifle.
Just saying. ^^
