Why no open all of area of vana diel Final Fantasy XI?

The Far East is no full open miss like 90% of the zone still locked

Distant Lands of the North Rhazowa is full locked

and from Far West and South still locked some area

why no just unlocked all area like the original plan?
It takes time, resources and manpower to create these new areas, FFXI is on the decline now and they've already decided to end major version updates.

Why no just made the Fusion Plan Weapons and Armor?

Armor Relic, Artifat , Empyrean, made Fusion Armor
Weapon Relic, Mythic, Empyrean, made Fusion Weapon
With dwindling player populations I doubt SE would want to create a massive skill gap in the player base, there are players out there who haven't done Vagary so don't have access to 119 Empyrean so by extension, this fusion gear and hell, most people don't have a 119 Empyrean to create a fusion weapon with.

More Job point
I like job points and I'd also love more but it's probably not going to happen now they have made 2100 Job Master and effectively set the end point, they could go back and change it but I don't think that's very likely.

More Store Merit Point
As in stored or increased categories? They just upped our maximum merit store to 75, that's pretty high already, always a possibility they'll increase the merit categories in the future too.

Also:

Why no able too spent merit/job point everywhere and no only in the moghouse
Probably some spaghetti code reason.

Why no just full access moghose from any zone outside moghouse
That would never happen, with current architecture that would create massive server load due to everyone needing to have their items across all storage accessible all the time and I doubt they are going to upgrade their equipment now.
