Either way, we can agree that the solution to that bug is not to make those optics collimating. The video shows that the optic is not collimated, your point that the sight gets misaligned is valid, but the solution isn't.
I agree that it's a bug, but it's because of the idle animation. The inherent weapon sway is not that idle animation (to clear it up for everyone else). It's mostly observed in prone and any slight mouse movement will correct it. We had similar with the crouched animation and ironsights in Arma 2.
That animation itself is what should be fixed.
In case of gameplay features, I do agree that scope shadow would be interesting. Right now we have the sway which doesn't misalign the optics and the way to control it with hold breath. I'd love to see those two interacting in some way. But that's a feature request for a different ticket.
The only reason I like that this happens (but still agree that it's a bug) is because it gives out some randomness and slightly misaligns the sights for scopes that are used for medium range enough that it prolongs firefights.
When in doubt, use marksman and sniper rifles to test.
I did, used the BLUFOR Marksman which is armed with MXM, HAMR and the IR laser by default. Observed the same with the EBR. I fired at the moment the maximum misalignment happened. Firing while they are aligned wouldn't exactly be testing the issue. :) Even with the SOS which is still 2D as the old scopes at 400 meters some random dispersion happens which is relevant as it contributes to the feel of the misalignment if you expect every round to hit at the same place.
Can we agree to alter the ticket to reflect that the problem is the idle animation in prone and crouched (I can't observe this while standing) in this case and not the scope itself and that the solution would be to correct the idle animation?
As for the assigned, apparently "Feedback" status assigns it to whoever set it to that when the author of the ticket replies.
