Server location for a MMORPG like FFXIV shouldn't matter too much unless there is an extreme (EU playing on JP for example). Key word is 'Shouldn't' mind you.

I've played Crysis (with MWLL overhaul mode) on multiplayer on a server in Germany from the East Coast of the US without much of a hitch. Pings were usually between 150-220 when doing so. Crysis in case some of you don't know is a First Person Shooter. The genre most heavily affected by Ping.

I've also played many other MMORPGs on servers on the west coast. Usually seeing pings of about 80-120.

ESO and FFXIV have some of the worst server performances of locally (in the US) based servers I've ever seen. Even before this move the server latency has been pretty intermittent while other MMOs (EQ, WoW, and others) have been fine. I think SE just doesn't have the experience with maintaining larger clustered server bases. And should probably consider devoting resources to remedying that.

I mean if Daybreak can double their server capacity (from 5,000 to 10,000) and add a queue for their progression servers for their 18 year old games. I'm sure SE could manage something similar.
