Unfortunately, the amount of times that I felt like screaming at the screen because I was in the middle of taking a crap or getting a drink, while someone crept up behind me to stab me isn't even worth mentioning. If you're in the middle of one of these processes (which can go on for a few seconds) you are unable to stand or move, even if you can see someone coming right at you. If someone was threatening to stab me in the face with an axe while I was taking a dump, I know I'd rather have the stains on my trousers than having my face hacked off any day. Still, it's fairly obvious that that skill here is to catch your prey in such situations and not vice versa, that didn't stop it annoying me though.
