Well, I have read the begining 4 pages on this one and figured I would add my 2cents:
UPS:
1. I think that it is about time that SE has been able to come up with a system that will encourage sale/new players to the housing wards. I like this because, on my server (Exodus) I have Mist, Ward 1, Plot 11. This was completely filled up in the first 3 to 4 months housing was started in 2.x. I do cruise the ward to see whats going on, and i have to say, not much has changed (outside) majorly in about a year. If most of these are abandoned, it will be nice to get new players who are active into the Ward.
2. This will encourage those who have unsub or left, to make the choice of what to do with their game account. Houses are not cheap. Furnishing houses is not cheap. the amount of time (gathering/crafting/gil farming) in order to fully outfit these houses is a major undertaking (casual players like myself) but still require a dedicated effort (hardcore players) in order to get them bought and outfitted.
3. This will encourage those who have houses simply to have them (FC's and Personal) to probably sell. The scavenger does allow for purchasing of sold items, or buy the retainers to store it if you aren't using a house.
DOWNS:
1. With the time limit (45 or 90 days depending on what thread your reading) I believe that SE has really taken a strong stance by siding with everyday casual players and a strong look to the raid only or hardcore raider community in game.
a. people do unsub because either the patch has nothing they are interested in.
b. Patches land around 90 to 120 days on average. A player will likey lose a during that time.
2. The current notes do not cover a player going into their house and logging out as a way to place hold being there. What happens if a player does this?
3. This does not provide anyway for real life to be taken into account inside the gaming world.
a. People who travel for work and only play on PS4 can't access it as regularly as a 9 to 5'er like myself.
b. Players who are in the military and are deployed/not able to access their house in game.
4. No definition for "Access" of house.
a. Most of us I think would agree that when we access our house is when we teleport to it.
b. Based on what I am seeing, we have to go inside (literally) the house to be deemed accessing the house.
Additional Things for SE to Do:
1. Players who seem to be wanting (ravenously) that what we have needs to be tossed and instant housing needs to be added. A couple of things SE could do to aid this crowd:
a. make the inn rooms specific to each player so that we all have an instant room/place to go. This would allow for a player to have a place they can make for themselves. This could also be setup so that the player can also invite other players to their inn room (a mechanic that is supposedly coming for personal housing sometime.)
b. provide (finally) places in the open world where players can access instant gardening and chocobo stables to players.
c. Since private rooms in FC houses are abundant, and not all use them (my FC, I am the only one using it, 512 total rooms available) let the FC sell them off. Since houses can be set to public access, let the FC sell off (in gil) private rooms not being used to players who want a place. FC sets the price for a private room with add costs for gardening and stable access.
d. If a single player ever gets (or already has, but doubt it) the ability to utilize workshops to build stuff, then FCs can also, for a fee (gil) rent out their workshops as well.
