I know this is a frustrating, terrible experience for a lot of people.. but there's no reason to attack each other so much :P It's not very likely that the devs implemented hidden timers to combat RMT ONLY because of one suggestion by an English-speaking player.
Yes, people have been waiting YEARS and that's terrible, but if Ishgard housing arrives next xpac, that'll be 24 (or more!) new wards instead of the 12 we got this patch. I know that's not enough, but I think this "we're optimizing and beefing up the servers" thing is also a sign of hope. FFXIV seems to be more successful than ever right now, so I think Yoshi-P can convince SE to invest in the technology needed to at least double the number of wards, and add Ishgard on top of that.
I think the neighborhood system is really cool and unique, the problem is just the scarcity (and, relatedly, the flippers, RMTers, and multiple-plot-owners).
If they manage to at least double the # of plots - yes still not everyone will get a Large - but at least everyone who actually cares about housing and wants to enjoy it can find something really cool. Plus it would be amazing for the player economy. They're not going to scrap everything they've done so far and do a whole new instance-only system, so this is a solution that can do some good and Yoshi-P seems to be working towards this!
