While I don't dislike kill counters as a concept, I feel that there's not enough information to look at beyond the counter itself.
I want to be able to inspect the weapon and get a complete list of everyone it's ever killed, how many times I killed them, the map(s) I killed them on, which class/character they were playing, and any special qualifiers (buffs, assists) that contributed to the kill.
And a bunch of sorting options for all of the above, natch.
