So it appears that you're on the enhancement side of the spectrum like me.
Nah, after reading all the comments and thinking about it, i'd say i honestly lean more towards whatever. Yes, enhancing content that was from live would be nice, but no more so imo, than potential updates or inclusion of custom content. It will really depend heavily on how well things are changed/implemented, and how balanced everything is as a whole. Short term, i'd honestly love specific areas to be focused on, long term however, i can't claim i'd stay if we didn't see new content in some shape, being worked on. Rate of the progress is debatable.
Honestly, my own preference would be to more harshly examine various aspects of the current system, skills, and world itself. Increasing pot size would be awesome, personally i'd like to see stacks of 50 to save space, allow me to actually keep multiple stacks for when i don't feel like grinding out for pots and herbs for the long/hard runs, and will give me more reason to use more than just the standard 100 pots i'm going to make otherwise. Unique race skills could use some scrutiny. A giant's stomp is only used for utility; aggro locking, sinking ground in zardine to dodge dragon meteor, exploration/fishing, but outside of the utility it's total and utter crap even at r1, while still using a lot of stam. Most of the time it won't even one shot a bat or gray town rat, for example, which are the most common and weakest enemies you see regularly in dungeons. As for a mix of world/system, i really would like to see something done about camping penalties and the weak/weakest ratings that apply to field mobs and certain shadow missions. Getting 0 xp for killing something is a horrible mechanic, and as you get stronger it gradually becomes more noticeable. We don't seem to have any real botting issues, and this is the main reason those features existed, so it would be very nice to see them done away with all together imo.
Those are examples of things i'd place priority on, but at the same time doing much without getting a general idea of how the community feels can be bad. A trial period may be nice to see how the public handles it, but generally gamers seem to get mad at such thoughts for reasons i don't quite comprehend, possibly because i'm hardly ever above tinkering with system setup and customizations.
