Well what do you hope to learn from that stat? Which gun is the most effective or most used in the game, because you get killed by it the most frequent? Does that stat says anything about your stats?
The only thing you can gain is having a global idea about gun usage and efficacy on the maps you frequent most. This would indeed be interesting to know as a global feature, but it doesn't really say something about your personal efficacy with the gun.
The stats you get now does... In a way. It tells you while playing with a certain weapon how many can you eliminate before being killed yourself. It is not very clear and doesn't calculate everything, but gives you a fair idea, doesn't it?
Anyways my 2 cents
Cheers,
