So, on nearly every Warlords of Draenor thread I've seen, people are assuming it is fact that there will be a considerable time travel component. Where does this come from? I've even seen people discounting theories by saying stuff like, "that won't be it because it doesn't involve time travel." Did I miss something, or is this just speculation after the most recent patch included the Timeless Isle?
It comes from a pair of leaks, one from China that mentions a number of old lore characters in their mis-translate-aganza ARG. The more concrete one nailed the name, but says it will be time travel focused with grom as the villain.
