Pretty simple, get to the quest Born to Shred in Talador (Born to Shred - Quest - World of Warcraft)
It'll put you in a shredded with a couple of abilities that one shot mobs and you're still granted XP. You don't have to complete the objective you're given. Tested last night just before servers went down, please let me know if you know its fixed after maintenance or already posted.
Thanks!
