Yeah, I agree Lev.
But it does tell you some basics about a persons ability as well.
For example if a person was just playing an arcade style, who cares if you die, Quake arena, you would think that their K/D ratio would suck.
Huh do I mean much like Jack and Beet. Ahh beet I wanted to lump you in there, but alas I cant. Good job, nice K/D history, you at least do fly to live. But jack ole boy, for god sakes your K/D was .9 last tour. You bet I do.
So then I thought ok maybe jack is just a little slow. So I looked at his Hit%eges. Low and behold they are respectable. It at least tells me that jack can hit the broad side of a barn.
So then I started thinking. Hmmmm a familiare pattern... can hit stuff but never lives. What does that sound like. One more time, kills stuff but kills himself too, alot. Wait, I got it. Suiciders. Quarter wheeling, arcade, unlimited death sweetheart bag fuel porking Jacal1.
Thats what his score tells me. So I agree, score is not perfect but The components of the score are telling.
