*Sigh*
Yes, the howling action can get old, especially when it's used so often.
The same thing occurs with roaring.
Anyhoo, I don't have much to say to this, considering most has already been said,
and all I can really say out of signifigance is that I have to agree with this little rant.
That and it really doesn't bother me, but then again, I'm rarely in a public map.
I usually go to private ones to hang out with friends.
Really, the best solution to so much howling is turning off the part of the game audio category that it can be heard from in the options, like Feareh suggested.
That's what I've used for the music so that I can still listen to videos while using FeralHeart.
Most of the time, howling or roaring is my or my friends' way of saying "Hey, we're looking for you!" Whenever one of us aren't paying attention to the game.
