I kind of feel the same way, even though I don't like to say I'm angry or anything. I really do appreciate the hard work that is put into the updates for The Sims 4.
However, I see how it can be a big problem to take away features like Whims that people like and replace it with another feature completely. I personally preferred Whims to the Wants and Fears system myself. Not to mention that I've seen a lot of people say that the game is unplayable with all the glitches from Wants and Fears. I'm hoping that they can be fixed soon, or that a system will be added which allows people to choose between Whims or Wants and Fears.
I actually haven't updated my game in a while because of the bugs and the new features. They make me a little nervous these days. I love playing my save files the way I like, and it has been a little disappointing when things would break and prevent me from doing what I like. So yeah, I guess I am also a little disappointed. I hope that these things will be fixed at some point so that the game can be enjoyed by everyone again.
