So - What you’re asking for, basically, is for Blizzard to sell you a game for $60 and then do absolutely nothing but sit on their hands and update it indefinitely with new free maps, characters, art etc. and never ever ever ever ever do anything that would make them money by selling optional, non game altering content packages in their events and promotional things?
Because it kind of sounds to me like you’re asking Blizzard to hang themselves for you because you like it that way, basically.
Company gotta make money. Don’t want the ticket? Don’t buy it. It’s hardly required content.
