you're forgetting they arent backed by big money now, how will they get money to make new content and pay their employees. stop being selfish, honestly I wouldn't mind another annual pass, because that allows them to gain some income and still get money for the game. other games like Rocket League or Fortnite use loot boxes and the like to gain money to be able to release free content. so unless you want that coming to D2 , you should be careful for what you ask for.
The free content updates wouldn’t have to be that huge. They could just add more lore books if they wanted to, and that might be enough to give the hardcore fans a run for their money.
