We had a discussion about this tonight, and while it might be interesting to read mortal feedback on a character, we really struggled to see how this would change anyones behavior. It is such an easy system to scam that we felt it wouldn't be a decent basis to give rewards on. Feeback would turn into back-and-forths or circular compliments to allies. The Battlefield forum suggests that too many players think all their enemies are bad RPers and all their allies are good RPers.
