There was a minor update to PTR notes, nothing super important at first sight but Blizzard considerably increased the amount of Valor Points you will get from Patch 4.2 Raid Instances.
You will now get the following amount of points if you clear up the instance in a given week.
|Players||Firelands Raid||Baradin Hold||Firelands Raid|
+ Baradin Hold
|10-Man||840 Valor Points||120 Valor Points||960 Valor Points|
|25-Man||980 Valor Points||140 Valor Points||1120 Valor Points|
