This is the easiest way to improve your skill and gameplay. Playing the DotA gets better from day to day, and beginning from now the latest of DotA AllStars and Legends of DotA maps include a completely new way to manage your ingame settings - a text-configuration file.
After having started DotA 6.88 or LoD once, a special configurating file will be created in your WarCraft III root folder (config.dota.ini or config.lod.ini). This file can be opened and edited with any text editor such as Notepad, it is a plain text file. We are recommend to use "clever" text editors, e.g. NotePad++ or Sublime Text, as they have syntax highlight for an easier navigation through.
