I would just try to avoid the Vallaki circus as much as possible. Even with Lizuca gone, there is a wall to wall crowd in the temple around peak hours causing the chat to scroll rapidly. If this is the zerg you enjoy, you may find the sheer spectacle fun. But there will be little adventure for you unless you abandon Vallaki and have great patience even during the off hours, the spawns just take too long to build up and all it takes is someone going in to clear it while it's still building to start it over.
Not saying it's perfect or even close to ideal for a majority of players, and it does last a pretty short time. Many come into the NCE under the impression that every dungeon will be available near constantly because everyone is so low level. But that's just not realistic. The easier dungeons are even more relevant during this time. Normally, there are no levels around, now everyone is, so everyone wants them. Most people will hit blind drive before hitting level 6, and some decide at this point to roll a new character and do it all over again, which has already happened.
Just how it goes. Mathematically it is feast or famine in terms of dungeons. There's only a handful of DMs and MPCs active as well, and they can only entertain so many at once, too.
