Yeah, sounds like a bummer. I could see having to update 5 separate folders taking a long time. I symlinked my folders which made the updating alot easier. I have 6 WoW folders. WoW, WoW1 2 3 4 5. I run all my stuff off of 1-5 and have the Data , interface, Account folders symlinked to the regular WoW. So when I update all I have to do is update WoW then copy and paste the new WoW.exe and 1 other file (can't recall the name because I am at work but it's something similiar) to folders 1-5. Win.
