2) A game is a work in progress.. Literally nothing of what Blizzard says HAS to be implimented. This isn't misrepresentation of goods, this is rather differences of creative management and time constraints. The fact that you argue over this proves to me that you honestly have not examined the law in regards to Intellectual Property, and are examining WoW under a miscatagorization of the type of good it is. Example; If Blizz says you are buying an apple, and you buy a box, and inside that box is an orange, that's wrong because it's a physical misrepresentation of the good. Now, if Blizz writes a book about "True Love", and in the end the characters fall apart and hate each other, that's not misrepresentation, even though you don't get the "true love" described. Now, WoW is a little more obvious, but still, time and management force things out. You are catagorising this misrepresentation on the basis of two items for warlocks that have been announced to have been pulled due to internal problems (which, ironically, we may be a factor of, but I won't go into it).
3) I'll agree that legal seperation of claims is one of the most basic forms of legal systems. This is honestly the first point you raise that I agree with. I dont quite understand how Antitrust law (aka, anti-competition, Microsoft "forcing" users to use IE as default despite having previously had an option to change at initial setup that they removed) coresponds to the pulling of an item pre-release in software. It certainly doesn't affect any profits other than MS's, and doesn't affect user's abilities to chose their brand.
I'm assuming £130 is the WoW annual pass cost. Now, three things: One: You pay for the game as currently is, and for the license to play on the servers. You don't pay for future content. Two: No one is forcing you to pay for all year at a time, and there's even a free test option. As far as Blizz is concerned, you try the game, say "this is for me", and pay for the privilage to play the live servers. Three: "Rival companies".... I hate to be "that girl", but what rivals? Bioware, who are monitising as much as they can out of TOR, and has an unprecedented loss in subscribers for such an ambitious game? Jagex, who struggle with real world trading and glitches. Turbine, who are suffering mass player drops (from what I can tell) from the game? The Dwarves? They hide in their mountain, caring only for their own greed. And I'm allowed to joke because of 4)....
4) No. No. NO. Do you seriously expect to be taken seriously in a court if you abandon a thread like this after a few days without clearly explaining your answers? If you had come to me with a brief, and I found this thread during my research, I'd probably say no. To quote wise man Walt White: You need to apply yourself. You never answer anyone's complaints clearly, and I know nothing I said above will have any slightest impact, so to anyone who actually read it, here's a cookie. Your words haven't been misunderstood.
My only suggestion, honestly, is to sit back, breathe, cancel your sub if you want, and play TOR, play LotRO, play GW2, play RIFT, play DCU, play Runescape and tell me, honestly, that BW, Jagex, Turbine don't mislead their customers as much as Blizzard. "Sift the world through the finest seive and find me one molecule of justice, one atom of mercy", comes to mind. It's all relative, and if you dislike the game, that's fine, and sometimes when we're desperate we want to get to a higher source of authority to vent our frustrations, but honestly, don't do it, you'll just make a show of yourself.
