Hello,
I think that there should be a limit to the amount of possession given to someone who has friends watching/supporting their side during a match. I recently played a home match that had the visiting team have 9 friends support them. This turned in to a 13% possession bonus for them. I feel that this is far too much of a bonus and it can significantly influence the game. Perhaps capping the bonus at around at 5% to eliminate any homefield possession bonus would be more appropriate in these situations so that managers with a ton of fans aren't able to manipulate a match.
What does everyone think?
