I did a search for this but it just said Invalid search so i decided to make a post for it, How to downgrade at any patch. Go into you're world of warcraft\data file, Usually located in C:\Program Files\World of Warcraft\Data. Delete the "Patch.mpq" file (C:\Program Files\World of Warcraft\data\patch.mpq) and then go back to C:\Program Files\World of Warcraft and run the repair.exe (C:\Program Files\World of Warcraft\repair) And click Reset and check files and wait for that to finish and you're done, It'll patch you back to 2.0.0, So just run the updates to w/e patch you want to go to and you're all set. Thank's for viewing my guide.
