Despite the fact it's played by millions of normal people around the globe, World of Warcraft players still get a bad rap sometimes. Peripherals like this don't help.
It's the official World of Warcraft "Tap Chat", which is a pedal. Which you can use to play World of Warcraft. Tap to chat! Tap to perform macro actions! Tap so you can grind and eat a microwaved bowl of mac & cheese at the same time!
Such laziness comes at a cost, with the Sound Blaster peripheral coming in at $US30. Then again, what is the price of hands-free grinding?
