(Speculation) Which classes get new sets in S20?

Been trying to conclude, logically, which classes will win the lottery for S20. Necro and DH is a given. Of the other two possibilities, Wiz or WD, I feel it should be WDs, although Wizards will have played Chantodos for three or four seasons straight by this point. WDs have been out of the meta for far longer, which is why I’d give them the nod, despite WDs having a far more recent new build.
As a Wizard, this is sort of a hard realization that we will get nerfed likely two seasons in a row and will have used the same set for over a year.

C'est la vie. 

Any else have differing opinions?

Personally, I’m expecting Demon Hunters and Witch Doctors to be the next classes to get their new sets.

Yeah. And Rats is going to be nerfed for sure, and thier current GR performance is pretty weak. Odds-on favorite for S20.
