Well if those changes include a downgrade in graphics I think it would be nice for the devs to talk about it openly. The fact that they don't NEED to do it has been pretty clear so far hasn't it. Just let people talk about it in circles on your forum, sometimes closing a thread and waiting for another one to pop-up. Not the best way IMHO but here we are.
People talk about many things. Some are unhappy with the combat system. Others with the Alchemy system. I do not expect the developers to explain to me why they chose to use that one combat animation that I don't like over another.
Also, I disagree there's been a downgrade in graphics, especially with the negative connotaitions that are attached to that word. Visually, the game has undergone changes - that's undeniable, lighting has been overhauled completely; a change some people like and others don't and one that the vast majority doesn't really care about. Volumetric effects are gone, for example, but we now have PBR and more detailed character models in general. There is no downgrade, it's just the game being in development - some things get improved, while others need to be scaled back a bit. It's just the reality of developing a game and seeing work in progress footage.
