Bashiok has just announced new valor point and conquest point changes coming with patch 4.3 that aim to de-emphasize the collection of valor points as a primary way to gear up for content. Both 10- and 25-man versions of the Dragon Soul raid will give 100 VPs per boss, down from 115 and 135, and Firelands bosses will only give 50 points each. The changes are intended to encourage killing bosses for loot rather than killing bosses for valor points to purchase loot. One can also surmise that the change is being introduced to give players more of a reason to try the new Raid Finder feature, where bosses drop loot with a unique power level.
On the PvP side of the equation, the number of conquest points received for the first daily Battleground is increasing to 100 up from 25, allowing players to work toward their conquest point caps quicker while not feeling like they have to run Rated Battlegrounds or Arenas. Both Rated Battlegrounds and Arenas will still earn players points more quickly, but this change should allow those players who prefer regular Battlegrounds to not be left in the dust.
