Q: How does matchmaking work for each season?
A: There are two matchmaking pools: matchmaking by rating (aka. MMR) and by rank.
When your star bonus multiplier is bigger than 1, or you are in Legend rank, you are (generally) in the first matchmaking pool; when your star bonus drops to 1, you are in the second pool.
Q: Why are there two matchmaking pools?
A: Since each player starts at the bottom of the ladder at start, we want fair matches for everyone (aka. win-rate close to 50%). At that time, your progression on ladder is protected by your star bonus, thus your net expected gain will be positive through the ladder. Once other players run out of star bonuses, matching by rank will allow for good players, or players who want to push themselves a bit, to be able to progress to a higher rank.
In short, having two matchmaking pools helps players progress in the ladder without having to grind as much, while still making most matches fair.
Q: If I “tank” my MMR at certain rank floor, will I be matched with easier opponents next season because you are matchmaking by MMR at the start?
A: No, in general you won’t. At the start of the season we will recover your MMR to certain threshold if it is dropped below that value, which is based on what your rank is in the previous season. Therefore, there would be no benefits to intentionally tank your MMR.
Q: How many stars bonuses do I get at the start of the season?
A: It depends on your current MMR and the rank you reached from your previous season, whichever gives a higher value. Generally, the minimal initial star bonuses you get for each rank floor you reached are:
