Regarding Hatred, the spec has just one singular problem for the nim ops - losing Maliciousness over smallest period of downtime, be it due to safe play or unavoidable mechanics. Tyrans Simplification? Maliciousness lost. Brontes Hand pushed in burn? Maliciousness lost. Etc etc etc.
This is the only reason why class is permastuck as cozy parsing meme spec and not an actual universally viable dps class. These changes just replace "cozy parsing spec" with "clunky parsing spec".
If you want class to be playable in actual ops, you need to keep amount of TTT procs for new rotation, which can be acquired with a 100% proc chance on Leeching and at least 66,6% on Thrash. And duration of Maliciousness needs to be increased to allow retaining the damage buff through enforced downtime.
