I don't recall ever seeing SE mention anything about never adding new wards again, but are they secretly doing just that or something? The last few updates gave us no new housing wards (and I figured the expansion would come with at least a few...). I'm sure a few of the less populated servers have open houses, but that is sadly not the case on the populated servers. Literally all of the housing plots in all wards (in all cities) are taken - and HAVE been - for a long time. They already screwed up by making personal and FC houses share the same wards, and now it seems they're not making up for it by consistently adding new wards.
I know other things are probably more important for them right now (such as this new expansion), but I would hope that they don't just give up on the housing system altogether (especially since there are tons of FC's out there waiting for a spot to open up so they can buy a house).
