I don't expect them to add every single thing that's requested, cause wtf let's be realistic here; that's not gonna happen.
It does trouble me though that what they're acting like will be a "great treat" for us is....a cinematic. An over the top cinematic reminiscent of Mortal Kombat, a game that has no actual substance and only ever gets purchased because people get a guilty pleasure out of watching the over-the-top violence.
What's worse, the cinematics have a downside too thanks to their genius coding of when to TRIGGER a cinematic. We all know the frustration of being hit with a killing blow before you even got a chance to block or to dodge, well now we might get them with arrows and mages aswell. Now, how the HELL does RANGED ATTACKERS having a chance to deliver a killing blow on you sound like a good idea? You'll get auto-killed all the time....Really pray that enemies don't get to use these as well....
My point? Updates like this make me worry about Bethesda's priorities. They seem completely ass-backwards, imo. They're focusing on the exact things that make my jaw drop; not because I think they're amazing, but because I think they're amazingly stupid to focus on and I can't believe Bethesda actually IS focusing on them instead of taking the time to design better perks, or yknow, give the game an actual [censored] plot.
You read quite a bit into their promise of ranged kill cams. And since enemy kill cams never happen unless the blow is actually going to kill the player, the only way you'd get a ranged kill cam would be if you were already at low health.
As for your point: I'm pretty sure the game has a plot, and I have a feeling the writers who spent the better part of the last 5 years working on this game agree with me. That's why they might ignore requests to "give the game an actual [puppies and rainbows] plot." I know I would.
