Last week I hit the Valor point cap (1000) and I had the Valor of the Ancients buff. This morning I logged on, and completed the Battlefield Barrens quest which awards 200 Valor points. I honestly cannot remember how many points did I have, but when I checked my weekly limit it showed that I had already reached 300/1000.
The other odd thing is that I still have Valor of the Ancients buff, considering I have no other characters with capped Valor points. My question is, is this a glitch that my cap is now at 300 or did I gain extra Valor due to my buff?
Edit: I should add that as of 10/7/2013 this does not happen anymore as the Valor of the Ancients Buff is not available when logging in after a reset. (I tried this today and got the 200 valor promised by the quest).
