Blizzard Downloader
It’s bad enough that World of Warcraft has been out for as long as it has and that it’s still extremely buggy and unstable (from what I’ve been hearing - I haven’t been playing that much lately). But their patching system uses this annoying BitTorrent based crap which basically kills my connection. Generally speaking, I’m fine with peer to peer applications and file sharing and what not, but it should be done at my own discression - not for something that I’ve already paid for, that I continue to pay for on a recurring monthly basis, and for something that I have to download in order to play something for which I’ve already paid for. Why should I have to donate my bandwidth so Blizzard can save money by not buying more patching servers and bandwidth to distribute the patches themselves? Grrr…
