Patchwerk is casting hateful strike every 1.6 seconds when it should be every 1.2. In Fusion’s log, the average HS interval was 1.65 seconds (147 seconds, 89 hatefuls).

while there is variance, hatefuls generally occur once every 1.2 seconds for the entire fight. the PTR version of patchwerk is dealing significantly less dps than it should be.
