I'm underwhelmed. On a very basic level, the approach to skills, class design, and other basics seems okay at least. Not perfect, but also not 4e. But the more specific content I see, the worse things look. The basic CS mechanic, for example, is a positive step, but nearly every maneuver associated with it is at least a little bit sketchy, and at the moment it's a fighter-exclusive class feature, not a system rule that fighters are good at.
The new casters were huge disappointments. The bestiary is very readable, but that's about the best I can say for it. The themes and backgrounds are not good.
I retained some optimism after the first release, but the second release dampened it significantly.
