I don't disagree that the new system is an improvement, not hard to do when the old system was so poor and outdated for current Hearthstone. However, do they really need to make more money when in a year of record profit (2019) Activision Blizzard laid off nearly 800 employees? They have plenty of money. And it sure as hell isn't going to the average dev.
Yes they need to make more money. It’s a business not a charity.
Stop crying. It’s how the world works.
