I think that is much better than the idea I had.

I was thinking along the lines of aa small but helpful buff that is enabled when you are down a man. Your towers or whatever needs to be taken out now have some slight life increase or the other teams defenses are lightly weakened. It has some balancing issues with this way as you don’ want to make it a normal way to play to lose one player to have a huge advantage over the other team.

As far as putting them in your idea into spectator mode I think that be great if they can have similar ranked or role type be the one having to sit out and wait. If a tank goes offline than I would hope a tank on the other team would be put into spectator mode. That way you try and keep things as balanced as possible.

Still no matter what people will try and find a way to exploit it. They could have a puppet account be in their team with lowest ranking possible to devalue their overall score and then just drop it at start of the match taking out a key member of the other team. In which case I hope the system has some kind of monitoring that will catch nonsense like that and just ban people.
