A common problem that occurs in so many mixes is what’s called frequency masking. A sound person wants a heavy bass sound and boosts the bass, lows and low-mids everywhere in the mix thereby masking so many of the high frequency sounds that make a mix intelligible.

On the other hand, another common problem is the sound person that boosts the same high frequencies in every channel thereby creating a harsh and piercing mix.

The goal of your overall mix is that no particular portion of the frequency spectrum should be over emphasized, but rather to achieve an even presence from low to high frequencies. We do this first, through range allocation and second, through channel volume placement.
