I’d like to see XP values awarded for performance medals too.  Seriously, if we get mythic medals, like ‘demon’ for example, I want to be properly rewarded for it.  I want it to contribute to my progression.  Right now, achievements like that feel hollow and overshadowed by the challenge system, reducing the gameplay value or ‘fun’ value of the multiplayer.  People focus less on performing well or playing objectives because of this.  It IS an issue.  A lot of people don’t play the objective, and it’s frankly appalling that there is a progression system in play right now that ENCOURAGES that.
