I know I'm sounding like a "one note" musician, but I absolutely hate the idea of deliberately moving away from realism to playbalance.
I hope HTC models everything as exactly as they possibly can. It's a simple fact that the excellent RL .50 round will easily and accurately travel over 1k and retain the energy necessary to kill/maim/damage at that range.
Now if we artificially make the bullet disappear at say, 800 yards, then we are tweaking realism for playbalance.
I guarantee you that if you are going straight away level, climbing or diving, at 800 yards even _I_ can hit you with .50's (I'm no great shot), You are not doing any ACM at all; you are providing me with an excellent chance to practice long range gunnery if I so choose.
So, is this a gunnery problem or stupidity on the part of the target?
What needs to be adjusted here is the perception that ranges over 800 yards relieve you of the resposibility to continue ACM. It doesn't.
Now, with net lag and the rest, you have to build in a buffer on top of that. The guys with the super 50 ping have this problem to a much lesser degree. My route in takes 11 hops and most of those are just under 200. I know this, having used Neotrace to watch it nightly, and I've adjusted my personal ACM rules accordingly.
I view anyone within 1.5 as capable of landing hits and thus fly as if those crosshairs were on the back of my neck.
Now damage, OTOH, is an inexact science. If you want to playbalance, this is where I'd look. (I'll go on record as saying the present damage model seems OK to me. It's very "playable".) No one really knows how many hits it would take to down a plane at any range because there's too many "it depends" involved.
If you get a .50 to the back of the head at 5 yards or 1000 yards, the results will be the same; the plane is going down.
If you get 50 .50's thru the wingtip, the effect should be negligible at any range.
It depends on where, how many, how far and how sophisticated the damage map actually is.
Obviously this area can be play balanced. That "other sim" is a perfect example. I'm not saying they did it right OR wrong, just that they obviously tweaked damage for playability to suit their customer base.
(They tweaked gunnery too, which I find strange/unacceptable if you're going to tout "bestest, mostest Realistic of all.")
Phew...enough already, my fingers are cramping!
