I`d rather see QoL features to housing than just more wards or even ishgardian housing.

-Mirror feature for forniture is a must already.
-Dye preview for housing items.
-Increased forniture for all kind of houses (+15, +30 and +50 for small, med and mansions, yard and interior). (Specially true for small houses yards which are bigger than mansion and medium houses due to their L shape).
-Increased variety of desings in common forniture instead of big shiny raid/trial items. Like, more oasis, riviera and glade based items, more fence, wall and roof options.
-Personal housing workshop with creation options of housing glamour.
