What I dont quite like of CDPR's responses is that they always say the controls are fine, or are working correctly, and variations of that, as if the worries people have with M/K controls were about them even working, they are not.
I dont like to speak for a whole community or things like that, but from reading the thread it seems universal that the main interest is in knowing and/or seeing that the controls are optimized and working as best as possible, that they are implemented in a way that a controller wouldnt be preferable for any reason possible whatsoever. Its not about the controls just functioning, its about how well they work, what options there'll be to tweak the mouse input and other things.
Honestly I'm not worried about playing TW3 with M/K because in TW2 they were fine or ok, and the team definitely heard concerns for the controller-centered decisions in TW2, so I trust them that now it can only be equal or better, not worse. But so far the subject does leave me a bit disappointed and simply unsatisfied so far.
