There is no need to be so negative about a feature that many would find really beneficial.
It's also something that is totally do-able if the developers wanted to do it.
I am not being negative. I am being honest.
The game is not even remotely designed for swapping characters between games. That is something which would need to built into the design from pre-production. It is not something to casually add in and hope it doesn't break anything (it will break a LOT of things).
This is not an MMO or a persistent world. It's an RPG based around taking a single group of characters from start to finish, with the relationships between them as an important part.
It's not intended for swapping characters randomly in and out, and I'm not wasting my time reading your explanation about how a different game designed with a different mindset and programmed in a different way did a thing which is not applicable to this game.
