I think the kills as a specific class and the kill a specific class in crucible might be bugged. I.E. sometimes when playing as a titan then kill a warlock I've seen "crucible [u]kills[/u] as a warlock xxxx/xxxx" show on the bottom of the screen. Edit: it shows actual numbers not x's/x's. It has happened on a couple of occasions. Unfortunately I don't have video, dates, or screen shots of this. Edit 2: scrolled down and seen others posting the same thing. Sorry. Thanks for the thread though.
