Sorry if this is somewhere obvious and I missed it, but I honestly can't find an answer anywhere. I just re-installed WoW (I accidentally deleted it a month ago and was too lazy to install it again until now.) and I went out to do some stuff. When I got back it had updated to 4.0.3, which I wasn't even aware of. What I want to do is downgrade from version 4.0.3 to 3.3.5, because to my knowledge there isn't, and may never be, a full working cataclysm repack by Mangos and it'll be a while before anyone else releases a stable core. Is there any way to downgrade without re-installing this giant of a game (20 gigs took a while to install -_-)?
