This may sound stupid, but the constant heart beat sound from activating DK dragon blood just UGH it messes with me, is there an addon out there to mute the sound?
There are quite a few sounds I find incredibly annoying in this game. I use an addon that lets me add a bind to mute / unmute the sound, but it doesn't really do what you want.
I for one would love to be able to mute the vampire mist form sound. Everyone uses it and I want to cry in pain, I don't know what setting I have on my headphones that makes it so jarring, but it makes my ears bleed.
I could also do without the continuous hurring from a dolmen when it's up.
And lots of spells have horrible sounds - like Immovable / Unstoppable or Annulment or Backlash.
