I don't understand the resistance to a subscription model.
Guild Wars 2 supports itself by putting all that shiny stuff for you to buy on the store, and it's not cheap either. A new armor skin is 10 dollars, and a new weapon can be about as much too. To even change your character's appearance costs 5 bucks, and don't get me started on how they managed to monetize the ever living crud out of dyes.
I, personally, don't like that. When I pay a subscription, I know that when I log in, I get all those weapons, all that armor, all the functionality and inventory space, everything for one cost up front. I don't have to play the "Let's roll the dice for the dye I want" at 2 dollars a pop. That dye will drop from a mob, in game, or be accessible to me through a tradeskill.
Subscriptions also give the company more peace of mind in the long run. They're more stable, easier to predict the bottom line of.
15$ a month is NOTHING, also. The cost of going to a movie for two hours of entertainment costs about as much. If the game is good, and has a wealth of content, you're going to spend dozens of hours a month on the thing should you have the time, and hundreds of hours a year, all for a little north of 100$ per year. Hell, a new game at launch costs about as much.
Again, looking for a good reason to rally so hardcore against something like this. If someone tells me that "They just don't get the time worth the subscription", I will ask if they have seen a film in the theater at all during that timeframe... because you just spent more for less overall entertainment.
