Another city gate neck would defnitely help for one of Thurgardin, Oggok or Halas
You could make it mega-easy to encourage it as a place for new players so they can bind at one site and then gate to wherever
Alternatively, you caould make it a short sharp quest for a high tiered group like Sadri which can be done in the time it takes to run back and forth between Sadri and MielB 3 times
Please no more quests requiring 8000 turn ins.
