I understand that but I don't think that is a good reason to forgo making change though, Everyone will benefit from positive changes it is true that some will benefit more than others but that doesn't stop it from being a positive change.
People who start doing favors now will have to spend less time, Should they not have shortened the time duration because everyone else previously had to spend longer? is it not "unfair" that player A spent 3 hours* to do what player B can do now in an hour*?
We make changes for the future not the past, we can only look forward in making things better.
(*hours are just an example and not reflective of actual time taken.)
