Replace Rhonin speech sounds by blank files, so you can walk around in Dalaran without hearing it over and over.
Do not install with Curse Client !
To install : Unzip the content directly into your World of Warcraft folder. NOT in Addons.
The final path must look like : C:\...\World of Warcraft\Sound\Creature\Rhonin\UR_Rhonin_Event01.ogg
