Back in September-November, Uldah was packed (much more so than it is today), but Limsa and Gridania were *also* packed with people bazaaring, crafting, @leve counter, etc. so in my opinion the main thing that has changed is the overall decrease in population of most servers.

And when there's less people overall, being in any city other than the central one is less "useful", ie I can't find anything in the markets, I may miss a recruitment "shout" for something I want to do, since there are not many groups being formed in the first place AND the party recruitment system is awfully designed and rarely used, and so on.

As for solutions, I would go for all of the below:
- Market wards merge - really what's the point of having 2 cities' MW that are almost completely empty.
- Server merge - to increase density of population and allow people to naturally spread out without feeling "alone"
- Shout across all cities (aka trade chat)
- Completely redesign party recruitment UI and usability. Introduce LFP flag, etc. so I don't feel like I have to be glued to Uldah to have any chance of finding a group.
