This is not a new video (recorded 4 months ago), but since Diablo 3 patch 2.4.2 introduced a lot of nerfs, I don't see how I will do better anytime soon. So here it is, Greater Rift 83, best I ever did.

The difficulty here is that I'm running 4 different classes, with different skills and spells. But, at the time, combining buffs from different classes was providing a much better result, compared to playing 4x the same class.
