Seems a bit ridiculous to me that you can't wiggle your finger mid-air.
I also feel that the vaulting animations are a bit ridiculous too. Far too many times I felt like I was in a position where I could have at least hip fired and made an attempt to survive. It shouldn't just be the reloads that are context sensitive.
Says it all in the title. I've had people who have watched my gameplay have said, "WTF kind of reg is that?" as well. Pretty sure it's not just an issue with me.
