It works pretty much exactly like any other server travel, but as an EU player who plays on NA, what I really want is to be able to travel to EU, since OCE is pretty much the opposite side of the world to me. I'd be scared to do any high end fights with a >300ms ping. Will be like the bad old days of playing Quake on dial-up except FFXIV doesn't do any sort of prediction
I have better delays with OC DC than NA DC, OC shows slightly a bigger number, but it feels more stable, than NA one with random spikes
Personally, I have managed to find several PF groups on OCE that I wouldn't normally find on JP, so I've managed to get closer to achieving some goals (like morbol mount)
I don't see many Japanese speaking players really that interested in traveling (happy to stay in JP).
One HUGE downside if they open travel to everyone to any DC is that cheaper markets like JP will get pillaged and abused by those with higher inflation (I remember how amazed I was when I moved from NA to JP at the end of StB and seeing how much cheaper everything was)
I think they should just keep it to OCE only, so that people wanting somewhere to mingle can do so without causing trouble for others (every DC has its own market, way of doing hunts pfs etc)
I've been incredibly happy to see some of my JP/Aussie friends again. The events have been fun, and even with the high ping (250-350ish connecting from EU) casual content is fairly doable.
I think if they do open the gates for other datacenters, the market prices will even themselves out after a while like it did with DC travel. Just simple supply and demand.
I've been meeting people from various Data Centers in Duty Finder. They're often just there to help out as well.
I was planning on visiting and checking things out but my impression from some of the posts on here was that we, from the NA DCs weren’t welcome so I didn’t bother.
Tried it out today and my first impression was that the server seemed really quiet. Queues were short for trial roulette and I had no problems healing and dodging aoes. Lag was very noticeable, though, so I wouldn't want to do any hard content on non-EU data centers.
