Surprisingly i haven't found a solid COLD impale demon hunter build out there, even though it's currently topping the leaderboards. So i had to create one indeed, especially when i am climbing the leaderboards with it as well. It's a lot of fun, and one of the most balanced DH builds i've ever played. It has tankiness, trash damage, elite damage, recovery. Everything. And you can even speedfarm with the same setup in normal rifts without any problems, so no separate setup needed.
