World of Warcraft Speed Hacks are fairly common on the internet and if used smartly can be very helpful when playing WoW. It's fairly easy to figure out what WoW Speed Hacks do by just looking at the name. As it implies these hacks allow you to change the speed of your character. There have been hacks in the past that can increase your speed by 200%, which would be hilarious, but you'll also be banned just as fast. The trick with using WoW Speed Hacks is to only bump up your speed slightly, to maybe 110%-120%. You'll definitely notice a difference, and you'll have the advantage, but it'll be slight enough to stop people from getting suspicious.
