There is alot of stuff they could be doing and adding that wouldn't effect the core. As I've mentioned before, adding outposts and camp functionality, more behests beyond the starter zones, more leve variation.

my main fear is that they are working entirely on core stuff and in 6 months at this rate when cores fixed, only then will they actually start on things to do beyond some of these bones. I hope and suspect they are working on some PVE but some letters and such give me bad feelings, like when they talk about working on core stuff and fixing it before they even think of any new content.
