Any advantage based on the kills you have in a match takes from the competitive edge of the game. In CoD, it's killstreaks. You get a handful of kills and boom! You're set to have an easier time killing even more. It's like the game says, "Hey bro, I see you've been working hard to get a few kills this life. Here, deploy this, and it will rack up kills for you, no aiming required! What's that? That chopper killed a few more enemies for you? SWEET! Here's another bonus item to deploy, even though you haven't actually shot at anything yourself since your first killstreak reward. Oh cool, that got you a few more kills. Here's a nuke. Go kill everyone in the game!" In Halo 4, it's ordnance drops. Unlike in CoD, this bonus comes from total kills and assists accrued in the match, regardless of how many lives it took you to get there. Plays out like so: "Hey there, little one. I see that you've finally gotten your fourth kill (and a couple of assists!). I know you've died 20 times so far and have no idea what's going on with this map, but here's a rocket launcher. Go get 'em, slugger." Oh how the mighty have fallen, where we had to know the map and time things for power weapons. Now if we derp around long enough, one will just be given to us. And then that little derp can just rocket the guy who's been out-BRing everyone the whole game, no contest.
