I hope as they release updates and maps that some new achievements come with them. I always thought I good achievement for matchmaking would be Grave Robber, it would be for when some one "steals" a kill. You know like in Lone Wolves you've almost killed this guy and someone else swoops in and gets the kill before you finish him. But to get the achievement you'd have to get like 5 or so grave robs in free for all match. I don't know just kicking ideas, get achieves tho...
