The following rules apply in regards to substitutes for the GLL Wingman tournaments:
- Substitutes are not allowed (this goes for the entire tournament)
- A team is allowed to play as 1 player for 1 game, providing they can guarantee that they will play as 2 for the remainder of the games. Should this promise not be held, they will be forced to sit out until the 2nd player returns. (This does not apply to disconnects)
- A player is only allowed to compete for one duo, and one region, during the GLL Wingman tournament.
