The fact that certain legends have louder footsteps than others really doesn't help either.
There's just too many varying audio queues and volume levels to balance and everything just blurs into one.
Maybe everything is working fine, but the clutter is so dense that we can't physically differentiate it all?
Take trios for example.
In any given gunfight there is 6 sets of footsteps, a potential of 12 separate weapons being fired.
6 sets of abilities/ultimates.
Back ground audio from other conflicts.
Environmental audio.
Door.
Ziplines.
Grenades.
Heals.
Revives.
Commentator announcements.
The ring.
Now that's just 2 squads fighting. You multiply that with each squad that gets involved and its literally just a barrage on the senses.
I honestly think its a balancing issue on various audio volumes thats causing this.
