That is correct, it's what players like antipika wanted in order to reduce lag.

And rightfully so. With the way devs want to go for boss fights/battles in general, Latency is a huge thing. Sure they can work around it, like they did with Garuda and Nael. But even those suffer from problems, and the dev team will never really be able to give us more challenging content, because they would have to work around the latency.

If they just abolished the package loss, I'd be fine with sticking on a Japan-based server, even if there was some minor lag.

It's a double-edged sword any way you look at it.
