So, as someone that plays this and ffxiv I would just like to point out to people continually asking when then will do merges why it will never, ever happen.

First on ffxiv, on this game there is a massive shortage of bank space, that is made worse with each update adding more and more gear. On that game you have to buy extra bank space in the form of retainers. Since people buy these for that purpose, Square have no reason to add more bank space and so they don't. That forces people who don't agree with it to do the same, which gives them less and less incentive to ever add any.

Now to the server merge issue:

The company sells server transfers, people pay money to transfer servers. They are even offering transfer server sales of 50% off right now, when a lot of servers are complete ghost towns. The same is happening on XIV, people pay for transfers from the dead servers, which gives them zero incentive to actually pay money to fix the problem.

So there you go, if you are unhappy with how dead your server is you need to take advantage of the current sale on server transfers. They are never, ever going to do a merge again because it's a means of profit as opposed to a large cost.

Stop asking when and get out your credit card or forever wait, just some helpful advice.
