What makes you think the development and maintenance of this game of this game isn’t a fixed cost? The same year they fired 800 employees, Bobby Kotick was awarded a $200 million bonus. The company has more than enough money for “game modifications and fixes”. And their costs have quite intentionally been slashed to the bone by letting go of literally hundreds of employees.
Once again. Your money isn’t going to make this game better or help the lives of anyone on this planet other than Activision Blizzard’s corporate shareholders. They’re doing just about as well in the game industry as a company can do. The current state of things is a choice on their part, not because they’re struggling to make ends meet.
