Ain’t that the truth? Unfortunately though, it’s not even that, but also Blizzard abuses the loyalty of their playerbase. Let’s face it, a lot of company would kill to get a fanbase as loyal as Warcraft’s, but Blizzard sees this as a method of putting in the least effort while still earning a good chunk of money.
Players can complain all they want about the monthly fee, but they keep paying for it, so why would Blizzard remove it? Players can complain about class balance all they want, but players still do content with them, so why would Blizzard care about it you add the MTX being their main revenue on top and you get a situation where Blizzard barely needs to lift a finger, getting massive amounts of profits with little work.
