But after importing an old character you can export it again to change the skills that the old character did not have, right?
The whole idea of exporting and importing is to be able to keep your name and appearance, and along the way you can also alter the skills. So, to export from an old version (to keep name and appearance) to a new version is then possible, and if you want to have points in the new skills I assume you can just export the character again, alter the stats, and then import it...?
