It would be nice to have a “LIKE” button in the after match report to indicate you enjoyed the game with such a player. Each FT member could give one like to either predator or other FT member. Predator could give 4 likes (so each FT member can get likes from a single match). Likes would be optional to give (player may decide to not give like to anybody). There should be some limit, to give only one like to the same player once per day (or 8 hours maybe?). You should be able to see if you get likes instantly in the after match report, but it should be anonymous who gave you likes. I think likes should not stack, you may see that you get 3 likes for example, but it would give only +1 to your total “like score”. Somewhere on the main screen you would see the number of likes and number of matches played. There may be a checkbox in options to make your like score visible to other players, but that is not necessary, as the system should mainly provide feedback to you.
I don’t think it should be implemented as given like to everybody by default, because then unchecking likes may be considered as dislike.
Of course it is not an exact indication, but it can be positive motivation for players to stay in the match to get their likes and some players may reconsider the way they play.
We use such feature in call centers and it positively motivates agents. They see a response from the client immediately after the call or webchat. It is interesting as such a simple feature can improve an agent’s mood as they work in a rather stressful environment (small workspace, your work is never done as you know there will be a queue of callers the next day, clients shout at you if they are not satisfied, etc.).
