I would like to say that I cant see emblem being based purely upon K/DR.
if you play solo and get to round 10 and do not buy quick revive, your game will end with roughly a 200 K/DR
which according to the estimates I have seen would land you with shotgun emblem (as long as you are patient enough to do this a fair few times)
and I think you will all agree round 10 is not the level of someone who is "the best" at zombies.
so the rounds you reach + headshots etc must deffinately have impacts on the emblem as they also help measure your skill
I've played three matches of tranzit on ps3 in public only so far( I usually play Wii u) and my rank is skull no blue eyes. No solo matches or anything. Just three 25-26 round matches. I just make sure I revive people if I can. Take lots of head shots and try to build things and open doors. Basically play the way I think that the game was designed to be played. Seems to work well. I mean I've gained a rank each match. I had the skull by the end of match two.
I can beleive the kill down ratio part as far as ranking up goes...
but the lose blue eyes or tally marks for not playing is total bullcrap.
I have played zombies everyday since it came out, IM not the greatest but on solo ill atleast get to 28-30 on a consistent basis.
Just the other day I logged on and had lost the blue eyes and a tally mark, for no reason at all that I am aware of as I have not missed a day playing yet...This was 4 days ago.. I have played every day since then as well, and have yet to get a tally mark back, or the blue eyes...It would have came back by now If all i had to do was play for a few days in a row..
I have 56,000 kills roughly
When I ranked up I decided to test with another game of solo with 30 kills and 1 down and I got deranked back to skull with knife which made it clear to me that it is kill down ratio. After that game I grabbed mustang and sally out of the fridge and got 2000 kills with no downs on solo and ranked back up just to be sure i dont get de-ranked again. I dont feel its a very good system though, I played far too much bus depot survival to rank up as quick as others. If you play solo a lot which I don't will inevitably help you rank up quicker than others so I was stuck on knife and skull for ages.
