I found a little Bug which give 50% in gaining valor points by quest
First Week, do your 1000 valor points to have "Valor of the Ancients"
Last day of the week go to the scenario "Celestial Tournament" and disconnect (I didn't test with other solo scenarios)
The first day of the second week, you are teleported to your home stone with "Valor of the Ancients" actived
It stay actived until you go in raid, dungeon or scenario. (For the one who do valor by quest as me only it is very usefull)
This week i will try to see on alt characters.
Nb: sorry for my very bad english
