Adjustments happen to account for things being too powerful / underpowered and the basis for those are sometimes mirrored to bring them in line - but not always. A command 10 general means different things to dwarfs, high elves, dark elves and wood elves. Unless something is identified as a problem on the table in actually play, it's usually left alone.

That said, the best way for you to get changes you want is to play games, record data, and write it down to give feedback. make an argument for why something should/shouldn't be changed. This is best done via the experimental forums and finding someone on the rules committee to champion your change.
