The Combat Coliseum event is based on a Rumble mode with special PvP matchmaking to ensure a better player experience. Matchmaking procedure: 1. Connection-based pre-stage - The lobbies are primarily put together based on connection. 2. Achievement analysis - It is determined what achievements the players have achieved in the Crucible. 3. Specialist evaluation - Achievements are categorized by markers. If someone reaches the marker, the achievement is considered fulfilled. For example, the "Trials Legendary" achievement requires at least 100 flawless runs. 4. Tussle Badge assignment - For each achievement, the player is assigned a Tussle Badge. Multiple achievements stack the badges. 5. Miscellaneous - If no Tussle Badge can be assigned, only the Competitive Crucible Division is shown. 6. The matchmaking tries to bring together a diverse mix of PvP legends. 7. The Combat Coliseum event begins. In-game, players can see which Tussle Badge holders are participating, who is leading, and who ultimately wins the Combat Coliseum crown. Each player is thus the patron of their PvP achievement faction. Summary: The Combat Coliseum event is an exciting opportunity for PvP players to demonstrate their skills and compete with other competitive players. The allocation of Tussle Badges for each achievement is a great way to motivate players to improve and showcase their accomplishments in the Crucible.
