These are both very cool locations. It seems like there are only a handful of things to do at each of them however. It would be nice if some new content was added to both of these realms.
That is it.
Just to point out what I enjoyed most, and maybe what we could have more of:
1. Blaustein : more seafaring adventures?
2. Ghastria could be expanded with a bigger underground network of theives/undead? Maybe one that requires you to retrieve a key in one den, in order to open a door in another?
