Alright so after testing some things out, I am pretty sure I know how the Ranking System works. I might be wrong, but it worked for me.
Kills/Wins/whatever DO MEAN SOMETHING!
Depending on how many points you have in each gametype, and how much you win/lose in each gametype determine your rank.
You play Elimination and all you do is play Execution, Warzone and Guardian. Well after a little while you will get your first rank and then possibly second rank. Once you hit your second rank, just playing Execution will not get your rank up. It will take A LOT to rank up again just playing Elimination.
What you will need to do is play different game types. What I did was play Wingman. I played a lot of Elimination and decided to try some Wingman. I was going to test my theory. Well when I played it, guess what? I got my third rank
So now I am working on my 4th rank. I am probably really close to it. I had 0 points in Submission and now I have about 20k in it. I am getting 30k points in ever gametype, and hopefully I will rank up once again. I don't know the set point goals of all the gametypes, but as far as I know, this is how it works.
Play all gametypes to rank up. Simple as that. I will post my points in every gametype below.
Annex - 35465
Execution - 43550
Guardian - 25492
King of the Hill - 37934
Submission - 25337
Warzone - 21210
Wingman - 30430
You are all welcome for this as well. Hopefully I have conquered the System
PLEASE CHECK TOP OF POST! WINS DO MATTER! JUST CONFIRMED.
