Going to defend the way SE handled this. Relocations free up spots in other housing zones which will allows new individuals OR FCs to purchase a house after the timer is gone.
I love being able to utilise relocations but can sympathise with how they would make new buyers very annoyed. If I was camping outside a plot waiting for 8 hours for the timer to go off and then some guy turned up and said 'my previous house is in goblet plot terrible if you want it' I would be very annoyed.
The current system isn't perfect but I still think its better than instanced housing because I like being able to see my neighbours housing. In the end theres just not enough supply of housing and hope SE can think of a better solution.
