I played a bunch of SnD since CoD4. In some titles, much more than other game modes. Before BO2, it was a great way to earn xp and rank up. Ghosts 2xp in SnR has been nothing less than awesome.
My point is, there are obviously reasons IW would make changes. Possibly to promote movement, keep killed players interest into the game instead of just waiting like you said. I'm not necessarily saying one is better than the other. But I will accept and be content with what the developers are offering instead of saying things such as ...... "How dare you remove a playlist without any reason.".....like the OP.
