Guild Wars 2

The ranking on leaderboards is determined by the Elo Rating System (Used in Guild Wars 1, League of Legends and the World Cup Etc.)

Rb Rating on the leaderboards for team B
Ra Rating on the leaderboards for team A
Ea Expected score for team A
RaN New rating Team A
K A variable that depends on your rating: 0-100=8; 101-299=7; 300-499=6 ; 500-699=5; 700-899=4; 900-1099=3; 1100-1299=2; 1300 + = 1.5
G Matches won(for the winning guild) and Matches lost(for the losing team)
Sa This is a 1 for the team that won, and a 0 for the team that lost.

Using the above we can produce two formulas

Ea = 1/[1+10^(Rb-Ra)/400]

For the winning team: RaN = Ra+k*G(Sa-Ea)

For the losing team: RaN = Ra+k(of the enemy guild)*G(Sa-Ea)

Keeping it short:

Beating a high ranked guild will give you a higher rating than beating a low ranked guild.

Playing in a game with more rounds will give you more rating.

Playing in a game with more rounds will give you more rating.

First of all you need to have an account.
You can make one by clicking on Register. On the “Guilds” page you can filter servers based on your matchup(check Matchups page).
If you go to a guild’s profile, on the bottom right side you can find the “Challenge” button. Click it to show the match settings screen, then confirm the settings once finished.

To submit a score, follow the next steps: Profile -> View Schedule -> Match Details -> Submit score. Also post a link to the game on Twitch / a Youtube link (listed or unlisted. It doesn’t matter).
This is to ensure the scores are accurate, and to keep the community happy.

If a video cannot be posted, for whatever reason, then you are free to use the discussion box on the Game page to post the result.

If a team fails to submit a score, and the winning team has to open a ticket on the forum, the losing (non score submitting) team will earn a -10 point penalisation.

You have until next matchup to submit your scores. It only takes 10 seconds

Once the moderator approves the submitted score of a match, it will take effect.
Its an instant process.
No delay!

If a guild doesn’t have any challenge for 2 weeks the decay will activate, meaning you will start losing rating once a week based on your leaderboard position. You will have to fight to be on TOP!
More details on titles based on rating comming soon.
