Can there please be some sort of restriction placed on housing for Stormblood?
Excluding FCs, there is no need for anyone to have more than one house per server, at the absolute most. Housing shortage is already a serious problem, and it doesn't need to be made worse by players with more gil than sense buying up multiple plots to the detriment of everyone else "because they can." I came across someone with seven houses on one server, and their reasoning was "what else am I going to do with the money?"
There should also be some sort of waiting period after buying your house before being able to relinquish it. A few weeks ago I was searching the aetherytes for housing plots to become available; I noted five or six over two weeks, and all but one was put up for sale the next day. Players desperate for housing are ending up having to pay double or triple to buy houses since some people treat them as a source of profit. Maybe have players be unable to manually relinquish land for 45 days, or impose a limit on the number of times a player can buy a plot over a given time period?
If a lack of housing is going to continue to be a problem for some time, it should at least be made less exploitable.
