personal stats...
 

Under personal stats, you should be able to see how many kills you've gotten with bombs(pipe, frag, gas, proxi, etc.) there should also be a high score thing for it XD i think that'd be pretty cool, seeing who's killed the most people with certain bombs:)

Most likely if they kept track of stats, all the explosives would be taken under one category.

i'd still like to see it :)

It wouldn't be a very hard addition. Would be cool too.
