Be careful, this can get you banned !
Hey, you can bug out one of the hunter talents, pathfinding, by logging in and out continusly while having aspect of the pact on. The extra speed increase you get from pathfinding stacks on itself with each log on, so in the end i had 500% run speed going.
So heres what to do:
YOU MUST BE HUNTER FOR THIS AND HAVE THE PATHFINDING TALENT MAXED OUT!
Then, you turn on Aspect of the pact and log in and out of the game (takes a decent amount of times, the more you do it the faster you go).
