I used to think the same thing until my buddy and I tried IB. Its actually alot more fun for me than regular crucible, don't ask me why, but it really is. It might be the goal of getting specific loot, I don't know. I used to die more than make kills until I read a crucible tips post a few months back. The single best piece of advise I took from it was slow the game down such that you're just walking from room to room, from one chokepoint to the other, being the aggressor instead of the prey. After awhile my k/d started going up. Mine still sucks but I consistently have more kills than deaths now, in IB that is. Once you see the game play out from a slowed down pace you'll start to get better. Stay back from your teammates a bit and start getting support kills. Hang back from the control points and don't take them right away, you'll get kills from the enemy team thinking it'll be an easy point to capture. It worked for me.
