They had to nerf it because it was too broken when I tested it on the PTR. Against targets with my DoTs the volleys were critting for 12k+. 2-3 hits and you’ll just absolutely obliterate anyone if you have good RNG or you force them into a corner so all the volleys land in the same spot.
You can Void Form and then Ancient Madness and shoot out double barrages and probably wipe out teams in BGs or arenas if you got good RNG.
I tested it again on the PTR and it still crits for 6k against targets and the new horror effect will be pretty strong.
If you stand in uneven terrain all the volleys land at your feet so on some maps DK gripping, stunning, and Shadow Priest using this ability will just instant gib people. It’s entirely an ability that skilled players will learn how to use and abuse.
