Well, this entire concept of using sound as distraction for certain actions isn't something what is used much in CS, since it doesn't have a significiant impact on results. I haven't seen many occasions when someone even utilizes it, the only occasion I can remember atm is SpawN shooting bullet at moment of landing after jumping off balcony in de_inferno. But having something like this would allow an opportunity for players to expand and utilize more on this skillset.
Well, I'd agree that roosters would be annoying anyway, but much depends on how they are implemented.
Anyway, lol. :D
