Played more of Bravely Second. In short, I like it, but it's not without flaws.
In long:
Overall, I think it's better than Default so far. The overall pace seems much smoother, Yew and Magnolia are fun in their own right and the control fixes (allowing for faster Brave-usage and better control of autobattle and encounters) make things more accessible. That being said, the new "streak" battles are a bit annoying since a major amount of whether you can get the maximum multiplicator relies a lot on luck. The German translation, unfortunately, suffers from a noticeable lack of editorial oversight. :/
