You misunderstand me, I'm afraid. My fear is that, if sub numbers tumble, the company will have even less reason to fix their money maker, and instead try to establish a new one. You know how it goes in this market, make product, enshitificate product, make new product...
You have gone off the other deep end, my guy. OP has never said they want quantity over quality, just a bit more to warrant subscription money. This game would be healthier if it had more gameplay content.
And you state that DT is lacking quality too:
So, according to you we are getting neither quality nor quantity. And customers should be happy to pay for that because then they can play other games?
There are people of this game, fans of this game, that want to play this game, spend time in it. Think about what may happen if more and more fans leave this game? There is a reason Yoshi-P has asked people not to retire, because more long lived content is coming.
