Well I got the knife when I got my K/D to 77, I recently lost it by playing Turned which messed up my stats and my K/D went to 30, then I played round 37 on farm and played some grief to get the gap between downs and revives little bit smaller (from 118 to 80) and got my rank back.
I have friend who has shotties and his K/D is 80+ smething.
I posted on a related thread a couple days ago. I strongly feel that your kills/downs have very little to do with your rank. I think it has more to do with your average round that you make it to. I base this on a comment one of the Dev's stateed about them not making new ranks because it would make it too hard for people to rank up. if the rank system was based on k/d then it wouldn't be any harder other than getting your k/d up. this leads me to believe that the game keeps track of all of your games and keeps a runnning average of what round you make it to. Of course there is a connection between your ability to get so many kills before you get downed and what round you typically make it to, but there is not a definite relationship. I tested my theory by playing 5 games in a row on tranzit when I very few games played. I had just lost my skull/knife icon and then got it back. after starting the game and then nding the game without getting any kills or downs 5 times in a row, I was deranked back to just a skull. This proved to me that kills and downs had no effect on my rank.
essentially every game you play, not just the most recent, are taken into account for your rank. Your average round per game. Good luck trying to calculate this value if you have not taken note of every game since you started playing.
and people will continue to talk about it until they know for sure what the ranking system is based on. Your reply is pointless and does nothing to address the OPs thread. I don't get how you can simply state "Everyone has figured oit out already. Ask anyone with shotgun ranks." and expect that to be an answer. I have several friends who have shotguns emblem while I have skull and knife, and not 1 of them can explain how they got the emblem. All of our stats are very close and mine are actually better than some of them. The exact thing/things that rank you up are not known. You obviously took this thread as an opportunity to display you need to belittle others, or at least pretend to think you are more knowledgable then everyone on here. If you infact know exactly what it is that allows people to rank up, why not post it?
