I have a theory that either our various caps for justice and valor points are too low, or the amount we get per activity is too high. I'll relate my thinking. I have several level 85 characters I'm running through the Dungeon Finder and Raid Finder tools. Clearing both halves of the Raid Finder Dragon Soul
gets me 500 valor; I then run four random heroics, and I'm capped. This means that playing my main any further that week is effectively a waste of time. (I usually cap my valors out before I even raid for a week, which makes raiding just about the gear, but I'm OK with that.)
My problem is, I like
my main. I'd play him more if there was anything to do. As it is, I tend to cap out on justice
points rather than run on one of my alts, and even then, they usually cap on valors as well. (At least two of them do.) I even sometimes cap on honor, and with the new conquest point gains for Random BGs, I could cap on conquest if I really set my mind to it. And while I understand why we have both weekly and total caps on points, it often feels like I'm being penalized for liking the game and wanting to play it.
