They did that to encourage people to do the objective. Without it, a lot more people wouldn't do them. Since what they did was something to help out the game, you complain about it. It sounds like you are saying they should just take objective based games out of the game, which in turn why are you playing a game mode that you are complaining about when there is something like deathmatch that you can play? Or are you one of the ones like like to sit in the back in objective games and get scorestreaks/killstreaks, which those are the type Treyarch tried to sort out. I respect what they did, but it's not going to really work. They would have to eliminate scorestreaks from kills in objective games for it to work.
