I'm not asking to turn FF14 from a MMORPG into an offline game, but I have a suggestion, so the storyline of 1.0 won't be forgotten/ignored: An offline remake of the original version of "FF14 Legacy".
This would be a remake of the original version for PC and PS4, so we can play those events. Obviously, the battle system and the dungeons should be reworked, since this remake wouldn't be focused into the online battle (though maybe it could have some online features, like FFXV is going to have).
This remake could have a way to transfer data to the main FF14, so we can get 1.0 lost rewards like the original Gobbue mount, the White Raven's earrings, the Legacy tatoo, or new ones exclusive from the remake: a mechanical White Raven mount (based on Nael's helmet), Bradamante...
Obviously, the main character should be Meteor or another character created by us, but in the lore, would be a different adventurer, since the main FF14's one didn't were at those events.
