My partner and I share a computer.

But I own the game on Windows and they own the game on Steam. Now that the new changes have taken place if you launch FFXIV from the Steam menu you cannot use a windows based account, and if you launch FFXIV from the windows version you cannot use a steam account.

This means we're required to have two installs of FFXIV taking up almost 100gb of harddrive space.

SE can you at least make a way to convert accounts between Steam and Windows - if you can't do it via steam you should lose some money and let windows accounts convert to steam.
