it's weird that no one talking about this aspect of QC, especially sounds are very important in competitive games

After watched the duel match between ZeRo4 and SyncError. I noticed a lot of problems about the sound effects

Let's take a look at this Unreal Tournament 4 duel video, you can "hear" the differences between those 2

UT4:

QC:

1. Unnecessary loud echo and ambience, overwhelm every other sounds
2. Weapon sounds have no punch, make them sound very weak
3. Lot of low pitch and high pitch sound effects, sometimes they're too high or too low, never "just enough"

Overall, the sound system feels overwhelmed (and weird), each of them try to fight the others, turn out to be a bunch of noises
You can compare with the UT4's to know what i mean, cleaner and more powerfull
