Just to throw my two cents in, I completely agree with 90% of what you said. The weapons disappearing, the scoping, Ragnarok. The only thing I disagree with you about is the guns. All the precision weapons, excluding the Carbine, are incredibly overpowered. The BR and the DMR deal so much more damage than they should. What about the players who enjoyed using his/her AR? The AR, Suppressor, and the Storm Rifle, in my opinion, are WAY too weak. If I'm in a firefight with one other player who has a DMR and I have a Suppressor, I don't stand a chance.
I'm not saying that the automatic weaponry should be more powerful than the precisions (because they shouldn't). I just think that they should be almost as powerful. Time and time again I find myself infuriated by the fact that an automatic weapon loses to a precision close-range. I loved Reach and Halo 3 to death, I really did. I could actually win a firefight against a BR with my AR (or against a DMR in Reach). That's what I loved about those games; everything was so even.
