Putting a different twist on it, and seeing as how they are opening up settlements outside of the city walls, I think it would also be a pretty cool idea to not only have linkshell halls inside the main cities but possibly outside too/instead. Not entirely sure how it would work but I quite like the idea ^^ Maybe linkshell "halls" inside the cities and some kind of more personal abode outside? Somewhere to raise our chocobos!

As for linkshell administration tools/controls, I have always supported this as a much needed function and am sad to see that this along with basic things such as loot distribution are still extremely low on the priority list
