^ incorrect, a hotfix is a patch that doesn't require an actual patch download, it can still be a minor download, we never upgraded to a new version of wow, it's still a hotfix.Just for everybody's future reference, a hotfix (at least whenever Blizzard uses it) is when changes happen on a live system. In Blizzard's case this happens whey they adjust something on the server, and the client goes on as if nothing had happened. That said, sometimes server reboots are needed to put the hotfixes into effect. Since we had to download something, this does not qualify as a hotfix.
Was it just hotfixes or a warden update?
Warden doesn't not need a patch to update it can be updated at any time while you have Warcraft running, a patch could contain software detection code but Im sure at some point some one in the know will mention it from their lofty cloud.
