Please have shared progression for couch co-op.

[QiamOnline]

My main reason I bought this game is because I want to play it with my cousins / nephews during the holiday seasons, which is like twice a year. I have one character that I play solo regularly and has many things unlocked, but it sucks that my cousins have to use a new character and grind the things my character already has. We don't have much time to spend on grinding and I am not grinding for 4 characters.

Like, what is the point of me having 4 characters if not for couch co-op? At least let me duplicate my endgame character or allow other players to select the same character. Thank you.
