Diablo III: Reaper of Souls

Gave it a few tries and I can't seem to solo Malthael on T4. The Death Shrouds end up covering too much of the ground and I die at the last 400m HP. Had to lower it to T3 and didn't get a Reaper's Fear. FML.

I think his HP scales more than any other boss in the game with each difficulty. The difference between T1 and T3 alone is insane. He just takes far too long to kill for the extra drop chance to be worth it.
