Do you think regional servers will help?

[Mikita]

Ask JP players how they experience the delays. they also have these delays when selling items or what ever, although the server is located in japan. Japanese players also have massive delays.

Not as massive as ours. In battles like Ifrit, if you're not standing on a crack, you don't get hit by it, unlike with most NA players getting hit by cracks even when they've run away and clearly aren't standing on it on their own screen.

Playing in Tokyo with a high speed fiber optic connection, you still get hit by eruptions even if you are well clear of it on your own screen. So I don't think distance from the servers and network lag are the only cause of that problem in this current version.
