This guy got it right. No I won't increase the initial footstep sounds.
The main thought of all this is to maintain the quality of very low freq sounds and at the same time make the powerful and loud. That goes to massive explosion sounds and also gunfire sounds. If there would be an even balance between exp, gunfire, ambient sounds and character sounds, it would sound very very unrealistic plus it would result in me cranking up the volume of the weapon and exp sounds cause people would say, they're too silent and it would cause these sounds to break.
Therefore I've found the absolute correct balance between sounds. Wich is very very uncommon in games. But I would say. Enjoy it as this beeing the first.
