Wush is simply TOO RNG to use to its full potential, plus Haste > Hit (especially with these RPPM items). Hit grants us 0 Haste as we'll just turn all we can into Crit, while we get 60% of the Haste from Breath guaranteed (since, well, you can only reforge 40% into Crit ).
Also something I think people vastly ignore: Crit Haste > Crit Hit.

- Breath of the Hydra – 0.525 RealPPM on damage/absorb from periodic spell. No ICD.
Besides the ICD being pretty cool IMO, I don't see how compared to Breath that it proccs "all the time". Breath rarely ever proccs for me, personally, so with a slightly bump in the RPPM, I don't see how it'll be that much better.
I'll agree that it's DEFINITELY not a DPS loss if it's to replace anything other than CY or Breath (again, debatable); UVLS, SPA Trinket, LotC, EoT, RoY, etc are all obviously worse than it, there's no denying that. The only problem I have is trying to line up a Combustion with HU/HS, Trinkets, and its own cooldown already. I really don't want to have to babysit stacks as well, but I would like to give it a try if a second Wush drops (well, a first one for our Lock, actually).
