Q: I'm a jerkface leaver. I can game this system by being a jerkface leaver right?
A: No. You incur elo adjustment based upon team result. We don't care if you left or not -- if your team won, you will gain points, if your team lost, you will lose points. You do however incur other penalties for being a leaver. This is because various measures to account for people leaving end up being gamable or cause weird effects on the system. For example, if we reduced the rating loss of your teammates if you left, then you might leave to help them preserve their rating. If we gave you a penalty even if they won, we would be "deflating" the entire system of ratings down over time, causing newbs to run into pros eventaully. Above all else, the system must be "capped" zero sum (so that, there is some inflation, but there is a limit). Otherwise, weird things happen.


I am curious about what that statement means. What are these "other penalties"?

Awesome breakdown. Where is the section about the cash to ELO adjustment ratio when bribing Riot employees? That part seems important.

The system guesses how good you are based on who you beat and who you lose to.

It tries to make matches where it thinkss you have a 50/50 chance of winning.

It knows pre-made teams are an advantage, so it gives you tougher opponents when you are in a pre-made team.

We did fancy maths to make the pre-made team stuff fair.

there.
