When the time comes, i will have to pick my LS or my gameplay.

Why would you have to pick that?

Your LS doesn't have to move. Unless they all want to move for a better ping, they can just stay where they are.

Keep in mind that system improvements are going to reduce the delays even if you're on a far-away server. There will still be some difference but unless you're a hardcore PvP player, it really doesn't matter much at all.

Unless something changes, all current players going to be on whatever server they're on now when 2.0 releases. People will have the option of moving (as far as we know), but they also have the option of just staying where they are, accepting a slightly higher ping, and being happy where they are.

The difference between playing on a server in japan and one in NA is not going to be THAT big. As long as the system lag is cut down, you'll still be able to play and do things that require movement (e.g. anything that's like ifrit cracks and lava) just fine with a <300ms ping, which is achieveable between NA and Japan.

In the current version, you don't really even notice ping because the server system is so convoluted there is a fair bit of delay regardless of your distance to the servers. Once that shiat is fixed up, you'll be fine.
