I am becoming more aware that the FBI has one very big flaw. That is, unless someone goes out of their way to give you the green thumbs up, you will not get them. Just like reviews, you only write one if you are disappointed with the product 9 times out of 10.
So over time your FBI will drop, now I did read the mechanics of FBI and quite frankly there needs to be a system where we need to rate our teammates.
I for one rarely report a player or commend a player, I just never do and I know a lot of players who do the same as me.
