Since 2.4 hit your PvP marks can now be 9 Dragons Gold turned in for honor. Even though this may sound like a good thing don't become a slave to the temptation of wasting all your marks, it becomes very frustrating in future knowing you have the honor but you need to grind bg's all day just to get the marks for that required item. As usual the marks even out anyway, the amount of time needed to grind the marks for your item will usually make up for the honor you need for that item, so unless your mailbox is exploding with 100's of marks try to resist the temptation of turning in your marks for honor.
