To those people asking that only wins should be rewarded, you clearly weren't here shortly after launch. Back then BW came up with the fun idea of making losing warzones "reward" 90 credits and pretty much no commendations. So what happened? Every time it looked like the warzone would be lost, everybody and their mom left the match. One faction geared up really fast, the other got stomped pretty hard, and people started rerolling to join the winning side.
Let's not do that again. If you play a warzone and participate you should be rewarded conquest points.
