There are about 3-5 camps of sunfury mobs that you can easily kill. To start, you should try small groups of maybe 3-5 for practice until you are more comfortable with the surrounding and the method you should use. Fully buff yourself up slap on an ice barrier then hop on your mount. Grab a small group of 5 with your mount and pull them onto a safe isolated spot where you can kill them with out interruption of your casting. Once you have them at your sweet spot, frost nova them down, blink away, bring out your pet if you need and start casting blizzard. Should they get close enough to hit you and your frost nova is not back up, use your pets. Freeze them again, rinse and repeat with blizzard, cone of cold or arcane explosion.

Once you get enough practice, you should be able to handle these mobs like a pro. You should be able to kill a group of 20 and up with no problem at all. Yes this does get very boring over time but it is still one of the fastest and most commonly used methods of Chinese World of Warcraft gold farmers and gamers. Keep in mind this WoW gold farming technique requires lots of repairs on your gears as you will be getting hit quite often.
