If this game would start with getting 3k~ valor every win you wouldn't mind because your mind would say its ok and normal and thats the way it is in this game right...
But i very much doubt that if they would make it FIVE TIMES HARDER!!! you'd pull your pants down and **** on your keyboard....
And who is to say this is easy? who says it should take an x amount of time to accomplish something, there aren't standarts set for such things, only in your head. If you have too much time on your hands dont mean others do....
Perhaps Bio did not intent for players to waste so much time on farming valors in the first place and now they fixed it?
Dunno man i dont see any issues here.
