Not sure why so many people care what someone said. Sure, it may not be true or the nicest thing to say, but it was just an opinion and it wasn't even that hostile.
Anyways, my KDR tends to change a lot so it's hard to say what my average death count would be. Lately, I've been getting around 2-6 but there are times when I hit double digits. If I had to guess, I'd say my average would be around 6 or 7. But again, it's hard to tell for someone like me.
