I completely agree with this thread. I've played the halo series since halo 1 and halo 2 and 3 were by for the best when it came to ranking system. Without a good ranking system there is nothing to strive for. The reason there is matchmaking rankings at all is to play competetively. Gaining xp and credits overall is stupid. I'm not 12 years old anymore, I don't play the game to make my guy look cool, I play because I want to be better than other people who play and I want them to know it too! I for one have already decided to wait to buy this game until I see how the ranking system works. If it's anything like the halo reach ranking system, I will be looking up the ending to the halo series on youtube.
