Seriously, companion in Skyrim, can you just STOP walking right in front of me when I'm lining up a shot with my bow? It's almost like you're going out of your way to block my target, because when I move over to adjust my aim to avoid hitting you, you move in the exact same direction!
I can't even begin to count the number of "critical hits" I've landed on my own companion because they don't have the sense to not stand directly in my line of fire.
