As long as mine is over 1.00, I dont Care . . . But its some crazy shit like 3.54 or somthing, I haven't checked in ages. I would prefer my old K/D of 1.01 though, just 'cause it looked cool. If it ever went over I'd then suicide a whole match to get it back. Might as well you-know. . .
Also A 2.00 K/D is quite good, although as someone said, can be easily achived by spamming and stuff. Although if you only play S+D then its a lot better, although now-a-days I mostly finish S+D (When I do play, which is only with mates, who dont play MW2 that much now) 6-2 or somthing, which is a 3.00 K/D.
And now that i've thouhgt about it, I probaly wont be getting BLOPS (Name is stuck now) Speacial edition, the old zombie maps are good, but I cant see myself playing them. I'd just go back to WaW, or play on the shipped ones.
