Ranking advice sought from Halo 3 players

Hi,

I am a casual player with limited skill. My KD is 0.81 overall but I have marginal positive KDs in slayer, extraction and dominion. Halo Reach was my first shooter and I was very bad but, have improved a little since then as my youngest child and grandchildren gave me the Halo 4 Guide book.

I understand that a completive ranking system is on its way some time soon in the new year (CSR). Further, I understand that there will be a different CSR for each game type.

For those of us, like myself, who do not understand what determines a CSR or Halo 3 rank (ie lvl 1-50), could those Halo 3 players who do understand what you actually have to do, and what determines a rank in each different gametype, please give some insight what I (we) are likely to expect and will be required to do in order to progress up the ranks for each game type.

While I understand that KD and obviously winning as a team in Slayer, SWAT and Team Snipers is what is important in those game types, I would imagine that KD is less relevant in say King of the Hill,Oddball, Capture the Flag and so on. Therefore,what does go into determining rank progression in those latter game types?

Cheers

winning. teammates who are dead all game don’t really help. communication is also very important. always put shots on enemies the second you see them. even if you don’t get the kill one of your teammates may be able to finish them off. if not they will still have to wait for their shields to recharge before they can do much.
