[quote name='DomLando']Are you talking about your skill going up or your enlisted Rank? Because the enlisted Rank is very easy to see. Like I said they have a whole layout of when you rank up. The skill well I would have to agree on that where it is a complicated system that nobody really knows how or when you go up or down. But EXP points seem to be gained everytime you win a match. Except in Lone Wolves it is usually the top 3 that gain EXP.[/QUOTE]
Skill level.
[quote name='lukems']Let’s talk about Ranking, EXP and Matchmaking in Halo 3.
First, your “Rank” in Halo 3 is the numerical value near your name. You’ll have a different number in each ranked playlist (social playlists don’t have a rank associated with them) and those numbers serve two purposes. First, and most important that number is our system’s assessment of your skill level relative to the Halo 3 player base. The higher the rank, the better the system thinks that you are. The second part of the “rank” is Service Record component, certain numerical ranks are required to reach different military advancement, General for level 50, et cetera.
Your rank and advancement through the ranking system isn’t a linear experience. There isn’t a “if I win 8 games in a row, I should go up X ranks.” Behind the scenes, we’re calculating all manner of information about your play style, skill, foes and party mates. Because the “leveling curve” isn’t a straight line, someone might get to level 30 in Team Slayer in 50 games, or someone might take a year to reach level 30 in Team Slayer. There’s no hard and fast rule to gaining rank aside from winning games, but even then, there’s no rule as to how fast you’ll advance. The system is infinitely more complicated than just a number being displayed in your profile.
Where “Rank” is the descriptor related to your skill, EXP is essentially a visually description of how much you’ve played. Depending on your finish in a game, you’ll earn an EXP point. Quitting, disconnecting, leaving a game are all cause for losing EXP[/quote]
