I usually just muck around in Crucible, seeing as it's an unbalanced mess made for the lowest common denominator of players... Before you say, "oh you're just bad at it." I currently sit at a 1.74 KD from dicking around with friends. The games I try, I average a 5 KD. This game is easy when you sit there and wait for your supers and make sure you lock down heavy ammo. Hell, playing like that, I've been managing a minimum of one 10 killstreak a game. How can anyone play such a mess? It's basically wait near your spawn for that heavy ammo and put the enemy at a distance.
