What's the problem here exactly? Do you realize Activision made people pay for 3 full priced games for one sequel (Starcraft 2).
How much does it cost to play WoW for a year? 15x12 = 180$ <- and that's without any added content.
How much money can you blow on free to play games like Hearthstone?
How much did people pay to play the 10 hour campaign for the Order?
I already preordered the basic edition and if the maps look promising then I will buy the pass. It's not hard. If you like the game, if you have fun with the game, then you pony up the money.
