If all that is possible then why on earth is using an existing character not possible? Copy over a few variables from a save and use it for a module - done! If the module is being started fresh then there isn't even any story or quest related stuff to get in the way, it's just move the character from one game to another.
They stated it some time ago.
I disagree with that. They are trying to sell this as the next evolution in RPG's that are akin to PnP etc. Something as simple as continuing to evolve, RP and develop a character that you have invested many hours in is a bog-standard requirement for RP games.
I never just take one character from one campaign to another and I really don't think this is a MUST HAVE, much less a standard.
Seems to me you complain about a easy of use functionality, you can do without it with no problem. They might add it later if they can and if everyone yells about. To me that is a "nice to have" improvement.
