Here's where I'm at with halo, and I say this with hope and experience. Halo 4 MUST have a successful ranking system. This is more important to halo than cake i to me. I cannot emphasize it adequately. The best system I have ever seen was the one from halo 2. You win a few-you go up. You lose a few-you go down. Additionally, it would be useful to have a time(NOT EXPERIENCE) addition. This would help prevent someone from keeping a 50 out of luck or boosting. If you don't play in a couple weeks or maybe a month, you start losing rank. This way bad players can't get boosted to 50, and then live on that reputation for the span of halo 4.
Now Here's where I'm at. Halo needs it. If Halo 4 doesn't get it, I won't get halo 4. I just no longer want to play a game where ACTUAL SKILL isn't important or discernible. So this is a plea to 343. I love halo and I have since CE first came out. I can see that Halo is in a coma. Revive it, don't kill it.
