Island Sanctuary as a housing solution ?

[Jojoya]

Where are there 20k active players? Because the largest server (Gilgamesh) lists 14.5k, and it's worth noting that 'active' doesn't mean currently playing, it means "characters that have finished 5.0". It's doubtful there are actually 14.5k people currently playing on Gilg.

(5 residential districts * 24 wards) * 60 plots = 7200.

That's literally more plots than the entire active population of Spriggan and Twintania. 7.2k plots is enough for every FC on the vast majority of servers + a large chunk of personals.

Unofficial census had Gilgamesh at 24k last summer. Player populations do rise and fall over the course of an expansion.

Your math is bad if you think 7200 houses will be enough for 14k players and all the FCs looking for a house, not to mention that the player population will have exploded upwards again by the time Ishgard housing is opened next year thanks to the release of the new expansion.

Not sure why you're bringing up the two worlds with the lowest population in the game. That does nothing to help the highest population worlds. Why should NA players be shortchanged when SE controls the number of worlds per data center and thus the number of houses available to players in those data centers?

Add in enough worlds to NA so we've got the same average populations as the JP data centers and we'd be okay. I don't see SE increasing the number of NA worlds from 24 to 40. Do you?

Set the ward system up so it expands dynamically by need per world and we'd be okay. Considering SE has already said they can't do that, I don't see that happening either.
