Not only Quest changes are based on greed

…but also Balance changes… So called “balance” changes can be very profitable to them, because they often push players to move to decks with cards they don’t have; often those decks have multiple legendaries; e.g. mid-Badlands everyone had to run monstrous highlander decks filled with legendaries in order to compete; or if someone is pushed to DK now the deck has at least 5 legendaries they may not have.
