Cosmetic Rewards for PvP Ranks

Not sure if anyone has brought this up before. Currently, there is little incentive to play PvP outside of getting better and levelling up in the Eternal War mode only. Operations rewards give you cosmetics you can carry over to PvP, and I think PvP players would appreciate some cosmetic rewards for levelling up your account and/or your individual classes. Even just one reward for max level per class would be something that would encourage people to grind PvP more and likely populate the Eternal War mode a little better.
