Different volumes between survivors grunts?

Does this not ruin the game? Yes, it boosts realism abit in the game, but isnt the game already very unrealistic? And I think making all survivors have the same amount of sound make better diversion between players, so they can choose whatever survivor they want without repercussions. For instance, I really want to play Jeff, but it is practically impossible as I die every match i play. However, when I play silent survivors such as Ace or someone, I notice a clear rise in match win rate. I see no point in keeping this in the game, and I would love to be able to play Jeff normally without running iron will or any other silencing perk.
