Whatever your position, mate, it's a fact that the patching process in WoW is one of the worst in the industry. The only other game with a similarly convoluted, inefficient, and time-consuming patch process is Anarchy Online (but is fortunately a much better game, making it far easier to tolerate the inconvenience.) Do a fresh install of WoW from the batllechest. Even before the pre-patches for Wrath of the Lich King, it would easily take a full night, since it downloads each and every patch incrementally (and that's on a 15Mb/s downstream connection). Now compare this to, for instance, any SOE game (setting aside their depressing habit of destroying really good games by listening to whiners and jacking up game balance to coddle them), or Final Fantasy XI, all of which have had consisted patch times of approximately 3-4 hours from a clean install, and have maintained that from launch day of the core game, up to and including their latest expansion.
That being said, I'll happily take almost any of the bugs we've had in EVE, no matter how serious, over the server stability on WoW alone. I've never seen an MMO with less stable servers, more server crashes, latency issues, etc, and that's including games still in the beta testing phase, than I have seen in WoW.
