Simply broken. I'm getting refunds.
Anyway, from the little I've seen so far, the game isn't such a big deal anyway. The graphics are on par with Champions of Norrath, which is a game from 2004. Gameplay mechanics might be better, but there's no way they could justify the price. As I said: refunds..
So my suggestion to Blizzard: drop this plan. Don't sell something that the buyers don't own. This is madness, and it will backfire even if you make a decent game, unlike Diablo 3. And Diablo isn't even an MMORPG, so I have no idea why they did this in the first place.
