Level 34-70 in 14 seconds in MoP Remix
As far as i know this is the fastest method to level to 70. if you are like me and do not know anyone who plays mop remix, you are reliant on heroic dungeon queue times and whether your team is good or not. On average 10-70 takes 2 hours. I saw a reddit post that inspired me to try this method and the person did it in 37 minutes.
