I can also attest that the housing market on Seraph specifically is a nightmare. I got lucky with a small plot in Goblet that only had 2 other lottery entrants, but every other plot I could find in every other area at the time was just about as bad as my old server on Aether.

I do agree that there are way too many instances of a single person or FC taking up far too much space. Unfortunately, it's unlikely that SE will do anything to combat this, because multi-estate owners are more likely to spend money on the Mog Station for extra retainers or exclusive furnishings. Pretty common MMO fare for the devs to never do anything to upset their whales.

Still holding out for instanced housing...
