Great idea.

AI'm assuming this would work over all user graphics settings. In Arma 2 people would reduce their video level in certain aspects to find gear on the ground and spot players easier.

The 'crack/thump' at 300m from a standard assault rifle round is about half a second.
Subsonic rounds would never be used at that range.

Fully agree with the requirement for a stance indicator. I too play only in first person and there are certain times when I simply have to check the third person view to make sure I'm in the stance I think I am as the 7 variations do not have enough difference as you move through one only.

I love the fact that we have the various stances, far more flexible to adapt to the environment, but it's become a real pain.
