That's a excellent point ! Learning by doing was and would be perfect to return in this game. Everyone would progress at what they want to progress at naturally by doing stuff. It feels more rewarding if I build alot then my building stats would be high, if sneak often then my sneak goes up, if i use pistols then that goes up... very fulfilling for the player.
The magazines could be used for crafting tiers or recipe unlocks so you wont spam craft things as what happened in the past which is why it was taken a away. I think the system Darkness Falls have is a great breakthrough and should be brought to vanilla, the action skills compliment the game very well. Then you could throw in the magazines for crafting idea with that and make it work somehow.
