Just don't use it if you don't like it. why does it matter if it does not affect you. New people need a crutch at times and old people like to play around with builds.
cause once players notice any decision of build could be undone, decisions become worthless no matter use it or not.
the point of role play is about you believe you are the character what build up by any decision you made. however, in this respec case, I can only believe myself as a Doppelganger
