As posted elsewhere, by other players:

Hamlets defence
Now: none.
Improved: Introduce Hamlet defence as promised many months ago. Hamlets defence would require players to defend Hamlets from waves of beastmen attacks or bandits. Reports from growing enemy forces would flow throw Eorzea through NPCs in cities and camps as rumours, hinting toward the time and which hamlet is going to be attacked next. Failure in defending the hamlet could result in NPC being missing and need to be rescued at the enemy camps, as well as damages done to the hamlet (giving repair tasks for Discipline of the Hand and tasks to clear the mess to Discipline of the Land).

Hamlets provisioning
Now: none.
Improved: Introduce task boards for hamlets too. Players doing the tasks reinforce the hamlets' economy, defence and more. Hamlets with lots of tasks completed would offer more items for sale, Discipline of the Hand guilds would be available to players (we can see alchemist guild icon, etc. over some doors in hamlets), there would mercenaries to help protect the hamlet during hamlet defence if the number of players enlisted is too low (helping to prevent a failure in hamlet defence). And more, giving more purpose to hamlets.

Character customization
Now: limited with character creation
Improved: Introduction of a greater ranger of colours customization, facial traits, hairstyles, voices and more during character creation. Once the character is created, hairstyle, some colours, some special features, etc. can be changed, added or removed at stylist shop distributed across Eorzea. Also, some customization features could become available through achieving certain requirements (from serious achievements to trival things to unlock new customization.)
