News · Rogue, Priest
Feint and Fade shed five times their Classic threat. Blizzard announced double.
Blizzard's deep dives say Feint's and Fade's threat reduction doubled. In build 70291 every rank went up five times, so rank 5 Feint drops 4,000 threat where double would be 1,600. Disengage and Cower doubled as announced.
Blizzard’s Oct 7 Rogue deep dive says 
Feint’s threat reduction doubled. The Sep 30 Priest deep dive says the same about 
Fade. Blizzard · Oct 7
In build 70291 every rank of both does five times what it did in Classic. The tooltips kept their Classic wording (“a large amount”), so the change only shows in the numbers under them. Game files · build 70291

Fade uses the same temporary threat aura as in Classic, so the threat comes back after its 10 sec. The cooldown is 30 sec. Game files · build 70291
Disengage and Cower doubled
The same deep dives call two more threat drops doubled, and those two are exact. Hunter Disengage went from 405 to 810 at rank 3, and Druid 
Cower from 600 to 1,200. Game files · build 70291
Feint, Fade and Cower have carried their new values in every beta build since Sep 16 (build 69876). Disengage doubled later, in build 70170 on Oct 1. Blizzard’s Oct 8 notes say its doubling “was missed” until then, on the server side. Blizzard · Oct 8
Torment, with no note at all
The Voidwalker’s 
Torment gives about 1.5 times its Classic threat on every rank: rank 1 went from 45 to 70, rank 6 from 395 to 600. No Blizzard post mentions it. Game files · build 70291
Which number the server uses
Threat is worked out on Blizzard’s servers. The server normally reads the same value the client carries, but Disengage showed the two can differ for a while. If the server uses these files, Feint and Fade are two and a half times as strong as announced. If it applies the doubling Blizzard described, the files are off and a later build should bring them down.
