I want to acknowledge that Larian has been doing a really good job releasing regular patches and hotfixes, and that with a game of this size across multiple OSes and a console, things will inevitability break as they're fixed.
Hell, no! This not how software is supposed to work! Normally it gets incrementally better, not worse. This is a sad testament to the quality of the product and a severe lack of QA. Imagine fixing e.g. the breaks of your car, that shouldn't affect your air condition.
Apart from that I fully agree. I would demand refunding the game, if I could. And I'm not that angry because of the terrible state of the game, I'm angry because of the lack of communication. Others comanies like Team Ninja or Hexworks do way better.
Both Wo Long and Lords of the Fallen were pretty clunky after release. Both companies reacted and released a full breakdown / road map of what they are planning to do when, which content they are going to add... That is community service and is more than enough to keep me calm.
