Halo: Reach may have some cool new features compared to Halo 3, although the ranking system is completely flawed. I had just gotten 31 kills in a Team Slayer game, carrying my whole team, whereas I was playing with a friend who had gained 6 six and went -9 kill:death ratio. I went +19, yet at the end of the game, they receive 1100+ experience, whereas I only gained 700-800. This is a extremely ridiculous, I'm quite pissed off.
