Judging by this poll, there are more than 15 people who are not overly enamored with kill cams. http://www.gamesas.com/topic/1365681-should-bethesda-patch-in-a-toggle-for-3rd-person-slo-mo-kill-cams-thread-2/page__st__120
I still agree that the frequency slider is the best approach.
But if you read the posts of most of those that vote, they love the kill cams and are voting for the slider only because choices are good. Most, by far, like the kill cams the way they are.
And using that "choices are good" logic, we should have a slider for everything anyone can think of that's in the game.
So really, with all the time and effort that appears to have gone into these kill cams, I would rather Bethesda leave them as they are and focus on other things.
Enough with the tweaking of stuff that's not bugged, Fix bugs and work on the DLC.
