Remember that fake bronze dragon/blood elf named Kairoz from Timeless Isle? If you have completed the Epoch Stone questline you will know that Kairoz has some sort of involvement with the Garrosh storyline.
At Blizzcon 2014, Chris Metzen talked a lot about this "friend" of Garrosh who saved him and took him back to Draenor 30 years earlier - In the youtube link /watch?v=4TqWCi3JAiA
As a mistake, a guy accidentally named the friend and called him Kairoz at 0:09:30. So we are actually helping this guy who later turns out to be our enemy.
