Why I earn less credits?

I was playing with an account were I was mitic and I remember I earned about 2000 credits on each match.
Now I am playing with a account were I am warrant officer grade 3 and now I earn about 800 credits per game.
I am playing with the same hability, why I earn less points?

I simply think that’s how the game works. The lower rank you got, the less credits you get. The best way is doing daily and weekly challenges.

The Credit system is very weird in Halo Reach as the amount of Credits you earn are also dependent on if you play on a Xbox live account. Here are few rules about credit earning in Halo Reach that I have discovered.

  • You will get Credits for playtime up to 10 minutes of the game and then you will stop earning credits from time. The amount of Credits per minute are constant for each playlist and will increase when you reach a higher rank (ex. Major III and Lt. Colonel)
  • Xbox Live GT will grant you around 100-300 Cr per 10 minutes playing - None Xbox Live GT will grant you around 2 000-10 000 Cr every 10 minutes playing - Xbox Live accounts has other sources for Credits but they are very limited. Requires Xbox live connection!
  • Campaign commendations from progressing them until you reach silver or completing milestones (iron, bronze, silver, gold, onyx) - None matchmaking challenges (around 1/5 of all challenges) - Matchmaking will also grant you other credit sources. Requires Xbox live connection and gold membership!
  • Completing Games (different bonus dependent on the playlist) - Slot Machine (random Credit boost for completing a game in a playlist which can vary from for example 100 to 3,000) - Firefight and Multiplay commendation for progressing them or completing milestones (iron, bronze, silver, gold, onyx)
  • I don’t know when you stop earning Cr for contributing to a commendation in Multiplayer or Firefight - Matchmaking Challenges
