Sorry if this is bringing back a dead post.
You raise a very valid point.
But rather than having the weapon completely dissappear until the sights are drawn, what about a delay? I have no idea if this is even possible but just consider and criticize me.
If you were to make an "unusual" movement ( i.e; looking at the sky ) the gun could be down momentarily, then come up with you rather then sticking the whole way. I think it would be irritating the have the gun down until the iron sights are drawn because that kind of defeats the purpose of FPWV.
However, the different awareness mode is a cool idea. If you created this feature, Would you have a hot key to change them or would the circumstances of your environment automatically change it?
