Let me start by saying that I don't agree with stealing software. I also don't like the blizzard model where you need to keep paying to play, but thats their choice and people don't have to play if they don't want to pay. That said, there are two things I would like to add:
1) Blizzard charge a fee for the game and I disagree with that part. People can pay good money for LK and not be able to play it. They should at the very lest include 30 days with each of the expansions. The fact the people pay for the game up front gives emu servers a small bit of legitimacy.
2) We don't just pay Blizzard every month so that they can "continue expanding the game". The money we pay every month allows them to expand the game, but also to fund their new MMOG and to net a cool $1 billion a year in profit. I am hoping that they will drop the prices in this economic climate but I doubt that will happen. An alternative would be for them to include all of their MMO's in the monthly fee and let people buy the games that they want to play. So you could pay $30 for the new MMO and $30 for WOW and then pay $15 per month to play both. Another MMO gets added and it would be the same. $30 up front and then it would be included with the $15 per month that you are already playing.
