Open League
From City of Heroes: Rebirth - Wiki
Defintion
Open Leagues allow other players or teams to use the Team-Up Teleporter to join events such as Trials, Task Forces/Strike Forces, and holiday events such as the Halloween trial. It is typical for team order and team numbers to be rearranged randomly (usually based on loading time) when joining as an Open League.
Joining the queue of the Team-Up Teleporter as an Open League grants an extra Astral Merit for Incarnate Trials and the Warmth of Prometheus buff power to all league members. There is no extra reward for joining non-Incarnate Trials, such as Death from Below, or holiday event trials as an Open League.
