Have you ever wondered how Company of Heroes 2 finds you an opponent when you play an Automatch game? Check out our latest blog delving into Relic's Elo+ rating system, and how you we find you your opponents.
Company of Heroes 2 uses a mathematical system to help arrange Automatch games, bringing opponents of similar skill levels together as quickly as possible. We call this system Elo+. This allows players to get into a game in short order against a foe as skilled as they are. When a player begins to search for an Automatch game their skill level is graded as an Elo+ Rating, and the computer searches for an opponent with a similar rating.
As the computer searches for an opponent it may begin to broaden the search if no opponent is found. Playing Company of Heroes 2 at times when there are less players online, may result in a greater chance of getting a match against a player whose Elo+ rating doesn’t match your own.
What determines my Elo+ rating?
The Elo+ system mathematically compares two player histories to predict what a player’s chances are of winning a game against another player. If you win, you gain points, if you lose, you lose points. If you’re victorious in a game against an opponent with a higher Elo+ rating, you raise your Elo+ rating more than if you win against a player with a lower Elo+ Rating. New players gain and lose points quicker so they reach the appropriate skill level faster.
Players have a different Elo+ rating per match type/race which is totally independent of any other stats in-game (level, XP achievements etc.). The first few times you play a match type/race, you will be matched against players with significantly different skill levels in order to quickly determine your true Elo+ rating. After the initial (currently 20) games, it will adjust your rating using a our Elo++ system.
How come I keep getting matched up with players with a higher/lower rank than me?
We don’t show players their Elo+ rating. What you’re seeing is a player’s total game level/rank which is earned through playing all modes of Company of Heroes 2. A player could reach the highest rank in CoH 2 without even winning a multiplayer game, since XP can be gained by playing the Campaign, Theater of War and even losing multiplayer matches.
It’s also important to keep in mind that rank does not directly equal skill. Don’t give up easily, you may just win.
What about team games?
We arrange team games based on the combined Elo+ rating of all the players on a team.// If I leave or am disconnected from a team match how is my Elo+ rating affected?
If other members on your side continue playing then your Elo+ rating will be raised or lowered depending on whether your team wins or loses after you leave. So staying in the game and helping your team win will help keep your rating higher.// What happens to my rating if I disconnect from a 1v1?
As with the original Company of Heroes we use a trust based system to determine who won if two players are disconnected. Our system will compare the number of disconnects that each player has had in the past, and determine which is the most “trusted” player awarding the game to the player with the least disconnections. A player who continually disconnects to avoid losing will become less and less trusted and be awarded less and less games.
What is Smurfing?
Smurfing is a term the community used in the original Company of Heroes because our system allowed players to create as many Profiles with unique Elo+ ratings as they wanted on their account. This allowed players to appear to be new players and continually play against opponents who were weaker than them. While some players liked this, it made the game hard for new players to play since they were too often met with a veteran pretending to be new looking for an easy win.
Company of Heroes 2 has no such Profile system, and thus players are unable to escape their Elo+ rating and pretend to be new. We feel that this gives new players a much better experience, and will be good for the long term health of the community.
Why do I still get crushed in games?
Our system attempts to match you with players who you have a 50% chance of beating. The more games you play using a specific faction and of a specific play type, the more accurate it will be. However there’s only so much we can tell based on people’s previous records.
Your opponent may have been practicing in another mode, for example playing against the computer to test out a new strategy. They may have been training like Rocky Balboa for the big fight, and it’s hard to beat anyone who’s just finished a good training montage. The strategy that your opponent used may just have been one your strategy was particularly weak against.
We can’t promise you down to the wire finishes every game, but with our Elo+ rating will keep you playing highly competitive games against players of your skill level as often as possible.
