Just found a very nice thing on curse, it's a "addon" that you place in the /Data folder in your wow map and it removes all combat sounds in the game (I think) I've always likes the music and npc sounds in the game, all in all it removes the following:
- Creature sounds
- Character sounds
- Spell sounds
- Interface sounds
Now if you for example want the sound of anything back, you just look it up in the folder and delete that spesific folder it's that easy.
Not sure how it works on northrend bosses though since I havn't seen any folders with their names on but hey, time will tell :D

I think this is something that might suit some people, but I would caution against it on boss fights as there are a huge number of audio clues as to special abilities or just plain ordinary combat skills etc in the fights. If the addon removed those prompts then I'd not be keen on it.
