Which means, we highly encourage players avoid deleting any 3.0.x patches until after the installation of Wrath of the Lich King.Of course if you would like to hang on to these patch files just in case you need to reinstall the game at a later date, you're free to do so, as it would save you the time of having to re-download them.
