To me the endings just feel unfinished. As mentioned before. The endings just feel like another plot twist before the next act.If that's the DLC we have to wait for - fine, i'll eat it up.
I have no clues about how such a decent company with a legacy of Witcher games could go so downhill so fast...
If it was two different people writing the main plot and the endings - i guess it's obvious who should get fired.
