Playing DL, I was confused when I saw stealth skills ("Take Down" and especially "Camouflage") on the top of the skill tree. I think it's not good, because I want to (and you too, maybe)... to have some stealth skills at the beginning of the game, because I'm not so "Rambo"-ed, and yet I can't throw zombies like tennis balls, I want to sneak and clean my way as quiet as possible. So I changed some skills in Fighter tab and in Survivor tab of skill tree (see screenshots).

By the way, I had changed levels required to get skills. Now you need to learn almost every skill in 1st "beginner's part" to get access to higher level skills (0-2 skills can be ignored, depending of tab (is it Runner, Fighter or Survivor)), so reaching skills is RPG-style now. In 2nd part ("Adept") you can pass little bit more (4-5 skills can be ignored there), for example, Grappling Hook is already available at 18th Survivor level.

Known issues:
 - Starting new game is required.
 - May cause problems with your previous save, if you continue the game instead of starting new one. (To continue your previous game: delete file "common_skills.xml" from "your documents"\DyingLight\out\data\skills\ folder)

Installation:

 - Put "data" folder in "your documents"\DyingLight\out\ folder
(Mod should be compatible with all versions of DyingLight. Tested on 1.5.2)
