Big fat -1 on this one, owing to the fact that the developers have far more important matters to deal with than helping you stroke your ego.
I believe they think call of duty explanation was a bit serious, when it was actually a joke. If I had an ego about getting sick ass dank no scopes, i'd play battlefield or a competitive shooter.I think this is a great idea, especially how Voca suggested it, toggleable, and off by default.
I'd imagine it would look something like this: (5) (0), I:5 T:0, 5 | 0.
Probably excluding the 0 kills part, to make it more simple, just (5) rather than (5) (0).
Simple, not too messy like the image in the suggestion.
No idea why people are down voting this just because of how it was pitched, it's not a bad idea.
