Tsulan, I am happy for you that you don't have an issue with the new update, but a lot of people are rightfully fed up:

• The new UI has been criticized as counterproductive etc before it even hit the PTB. But instead of changing it (not even BACK, just changing the layout and icons, that was all people asked) the devs pushed it through and are now clambering to do some damage control, after pretty much lying to our faces about how they cannot change it back.
• The new animations are as counterproductive to the gameplay as is the 'new' UI. DbD is a game where having the movement end when the animation ends is not a good idea because you often have to react quickly.

All in all people are angry that bhvr seems more focused on pleasing some investors that have never played a game in their lives by making the game LOOK great and REALISTIC (read that with as much vitriol as you can msuter) but at the costs of making the game unplayable because the look (and its performance cost) hinder the actual gameplay.

Add to that the general sense of the devs mocking the community at every turn, the general lack of communication, etc and... people absolutely have a right to leave for good.

There are games that have a smaller team, a massively bigger playerbase and yet run better, look better and are more fun. Just they are a different genre. BHVR should honestly not be rewarded for the shoddy, uncaring demeanour they display towards the community.
