Ranked

The matchmaking system for ranked games in career works like this:

1. Get the 100 oldest available ranked matches matching these conditions:
   1. Opponent's league has to be between your league - 1 and your league + 1
   2. If opponent's league is different than yours: league score delta has to be lower than 100 points
2. Remove matches matching these conditions:
   1. Opponent has already been played in the last 5 minutes
3. At this point, there's 2 possible cases:
   1. There are some matches remaining:
      1. Sort the remaining matches using these comparison rules:
      2. Opponent with the closest league first
      3. In case of equality: opponent using a different IP first
      4. In case of equality: opponent never met or met the furthest in the past first (considered equal under a 10 minutes delta)
      5. In case of equality: opponent with the closest league score first (considered equal under a 10 points delta)
      6. In case of equality: oldest match first
      7. Take the first match of the sorted list and join it
   2. There's no match remaining:
      1. Pick a random map from the map pool (see below)
