As said before the game does not really understand what a game licence is even less then it does on live atm, all my beta chars are on there own Battle.net accounts so can not get we have to wait for a blue post about this is just been data mind. but all in all all your chars are all your "alts" but one ;) unless you do not play battle.net wide.
Battle.net is there for players that's needs more char slots so that's why the changes seem kinda fun for us :)
