I'm not sure what you're talking about Jeneralben but I don't know any other game in which you have to manage units/companions that use this "ghost' (as you call it) chain system but DoS and DoS2.
In other games you select the character(s) or unit(s) you want to move and move them exactly where you want. This is how it works in all cRPG and in strategy games in which you can sometimes have tons of units.
In BG3 you only select 1 character and move him + you always have to choose who's following or not, which lead to many issues (more clicks, less intuitive, harder to properly control your characters, uncontrolled companions movement,...)
