When you're team is out of revives, and you're waiting for your team to find another revive in a bucket, the game will send you to orbit for being "idle'. Well, you can't move since you can't respawn, but the team still has time to earn another revive. It doesn't make any sense to remove a player from your team while the team still has an opportunity to find a revive, or to mark a player waiting to be revived as "idle." This most frequently occurs between the second and third encounter of Lawless Frontier matches.
