In World of Warcraft, there is a weekly cap for all points you can earn (justice, valor, honor and conquest points). Is there a way to increase the cap for any of the points? If yes, how?
It is different for the different points:
There are no weekly caps for Honor and Justice points.
No, there is no way to increase the 1000 Valor points per week cap.
The Conquest point cap is depended on your Arena / Rated Battleground rating. Further it rises automatically over the course of a PVP / Arena season and is the sum of your unused weekly caps over the season (if you have not earned any Conquest points yet, you should have a cap of around 25.000 by now).
