Just saw this in the latest iteration of patch notes.
The maximum number of Valor Points which can be earned in a week from any and all applicable dungeons and raids is now 980, down from 1250.
- The maximum number of Valor Points awarded for completing Rise of the Zandalari dungeons remains at 980.
- The maximum number of Valor Points awarded for completing Heroic dungeons remains at 490.
- The number of Valor Points awarded for killing a boss in the Firelands is 70 in 10-player mode, and 90 in 25-player mode.
- The number of Valor Points awarded for killing Occu’thar in Baradin Hold is 35 in 10-player mode, and 45 in 25-player mode.
- The number of Valor Points awarded for killing a boss on Heroic difficulty in The Bastion of Twilight, Blackwing Descent, and Throne of the Four winds is 35 in 10-player mode, and 45 in 25-player mode.
Looks like Blizzard’s trying to slow down the valor income rate significantly. Instead of getting a chest piece in two weeks, we’ll have to wait three weeks. Not sure if I like this. There’s not much of a point to go back doing Blackwing or Bastion on Heroic with the reduced valor there either. Well, unless you’re going for completions sake.
EDIT: Should be Valor right? Darn this split English language thing!

[...] Yesterday we got news that the valor cap is being lowered from1,250 valor points to 980. This may seem like an insignificant change by itself, but it comes among a series of others as well. [...]
