In patch 4.3 we’re changing the daily battleground (BG) to reward 100 conquest for a win (up from 25). In addition, every non-rated BG that you win will also give you 50 conquest. There is no limit to how many BGs you can run this way, up to the normal conquest cap.
Our intent is to start acting even more on our Mists of Pandaria philosophies of encouraging players to approach the content they want to, how they want to, and be able to work toward meaningful player progression. Arenas and rated battlegrounds will still earn Conquest faster, but with this change you can now work your way up by running normal BGs, if you so choose.
