let's get the facts straight: with the actual favor system, the favor points you gain are in 50% of the cases not related to the importance you had in the victory of your team:
-if you play an healing sedna, you are a bad damage dealer, but you are essential for the team (a lot of time and survavibility gained) but you are a lot less rewarded than if you were just a standard assassin
-if you play a rook tower farmer/tower eater, the chances are also that you will gain only a litlle favor points (buildings if you are lucky..., and it is not an obligation, since you are likely to only push one lane and lose a lot of time against a row of tower, whereas it is easy to destroy isolate towers).
-if you play the oak and you focus on your shields to bypass the towers and lock your ennemies portals, or save your allies, you are also playing an important role but aren't rewarded for it.
So i really think that the favor system is totally broken; and only rewarding one player??? i don't see the point, if i spend 10k gold in the citadel, and my teammate spend 11K, he is rewarded and i am not. Why is that?
