It doesn't mean your defensive, it just means that you were camping an objecrive, and killed people who happened to be near it. It's not a Stat of skill, it's a Stat of experience.
You don't have skill, you have some experience doing shit [b]everybody[/b] does.
Honestly, shut up. Have your momma teach you humility. Read a book or something. I recommend [i]The Alchemist[/i] by Paulo Coelho.
