You want boring? I pretty much exclusively play TDM. Fuck the other modes.
Speaking of K/D's though, I always find that they mean absolute jack shit in any mode but TDM. And that goes for any FPS. I hate it on Halo when you've got a game of team King of the Hill or something and somebody ends on about 35 kills and 4 deaths but their team has lost by a fucking mile. They're basically one player down as he's only interested in getting up his own precious K/D stat.
The only stats that matter are the stats that actually contribute to getting a win.
Gah, that's turned into a bit of a rant. Not really directed at you so much as every fucker I've ever seen show up in a game and just score easy, meaningless kills while watching their team get destroyed.
